Here you will learn about pictographs, including constructing, reading, and interpreting them.

Students first learn about pictographs in 2 nd grade with their work representing data in measurement and data. They expand their knowledge of analyzing and representing data as they progress through elementary and middle school.

What is a pictograph?

A pictograph or a picture graph uses pictures to show data. It is a method of data visualization.

Tally charts can be represented by pictographs. To draw a pictograph, you use a graphic symbol that goes with the frequency or value. The key of the pictograph explains the numerical value that the symbol represents.

A pictograph design can be constructed using a table with two columns. In the first column is the name of the group or category, and the second column features the graphic symbol.

In the above example, the tally chart below shows the frequency of the data for the favorite season for each of Mr. Johan’s students. Let’s represent the tally chart as a pictograph.

The picture (symbol) of the smiley face represents 1 vote. In this case, the number of smiley faces is equivalent to the number of tally marks. 7 students liked winter as their favorite season, so on the pictograph there are 7 smiley faces for winter.

The pictograph makes it easy to answer questions such as, what is the number of students that prefer summer?

This pictograph represents the amount of fruit eaten by one person per day over the course of one week. Here, each green circle represents 1 piece of fruit and so we can see that 4 and a half pieces of fruit were consumed on Monday, 2 pieces of fruit were consumed on Tuesday, etc.

History of pictographs

Some of the first pictographs were found in the Americas. Have you been to the Petroglyph National Monument in New Mexico? Here you will find some of the first pictographs ever created.

Petroglyphs are rock carvings or rock paintings, which are also called pictographs.

Approximately 90 \% of the national monument’s petroglyphs were created by the ancestors of today’s Pueblo people (Native Americans) who lived in the Rio Grande Valley since about 500 \, AD.

Common Core State Standards

How does this apply to 1 st grade – 6 th grade math?

• Grade 1 – Measurement and Data (1.MD.C.4) Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
• Grade 2 – Measurement and Data (2.MD.D.10) Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put together, take-apart, and compare problems using information presented in a bar graph.
• Grade 3 – Measurement and Data (3.MD.B.3) Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs.
• Grade 4 – Number and Operations – Fractions (4.NF.B.3.b) Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, for example, by using a visual fraction model.
• Grade 5 – Number and Operations – Base Ten (5.NBT.A.2) Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole number exponents to denote powers of 10.

How to read a pictograph

In order to read a pictograph:

Read the key in order to find the value of each symbol.

Interpret the data to answer the question.

Use this quiz to check your 1st, 2nd and 3rd grade students’ understanding of representing and interpreting data. 15+ questions with answers covering a range of 1st, 2nd and 3rd grade represent and interpret data topics to identify areas of strength and support!

Pictograph examples

Example 1: read/interpret pictograph.

At a family reunion, Dara took a survey of her relatives’ favorite type of pet and made the pictograph below. Which pet had exactly four votes?

Each paw print symbol is equal to 1 vote.

2 Interpret the data to answer the question.

Looking at each of the rows

The rabbit was the pet with exactly 4 votes.

Example 2: read/interpret a pictograph

The pictograph below shows the favorite sport of Ms. Barr’s class. How many fewer students like baseball than soccer?

Each ball symbol is equal to 1 student.

There are 8 ball symbols for soccer which means 8 students favor soccer. There are 6 ball symbols for baseball which means 6 students favor baseball.

Comparing the ball symbols in each row, you can see there are 2 more ball symbols in the soccer row which means 2 fewer students favored baseball than soccer.

Example 3: read/interpret pictograph

The pictograph below represents the number of cars that parked in the train station parking lot over the course of 7 days. How many cars were parked in the lot on Day 4?

Each car symbol represents 10 cars.

On the pictograph, Day 4 has 5 cars.

You can skip count starting with 10.

You can add,

10+10+10+10+10=50

There were 50 cars in the lot on Day 4.

How to construct a pictograph

In order to construct a pictograph:

Make sure the table has the correct number of rows.

Label the table.

Make a key.

Count the graphic symbols for each row.

Draw the graphic symbols into the pictograph.

Example 4: construct a pictograph with graphic symbol equal to 1 unit

Use the information in the following table to construct a pictogram of the number of water bottles drank per day over 5 days.

There are 5 days on the tally chart, so there should be 5 rows on the pictograph.

Count the number of graphic symbols needed in each row.

Place the graphic symbols into the pictograph.

Example 5: construct a pictograph from a tally chart

Four students were playing a game of marbles. The number of games won is recorded in the tally chart below.

Draw a pictogram of the number of game wins. Use the key provided.

There are 4 people, Anna, Bella, Charlie, and Derek so the pictograph has 4 rows.

The key is given.

One circle represents 2 wins.

Example 6: construct a pictograph with graphic symbol equal to a large value

A tile manufacturer is calculating the average number of tiles the factory produces per day over the first 6 months of the year. Below is a table of results.

There are 6 months, January, February, March, April, May, and June so there should be 6 rows.

Since there are four diamond shapes in the symbol, each small diamond equals 500 tiles.

In order to figure out how many symbols there should be in each row, divide the tally for each month by 2000.

\text { January }=5000 \div 2000=2.75 → 2 full symbols and 0.75 or \cfrac{3}{4} of the third symbol.

\text { February }=7000 \div 2000=3.5 → 3 full symbols and 0.5 or \cfrac{1}{2} of the fourth symbol.

\text { March }=6000 \div 2000=3 → 3 full symbols.

\text { April }=7500 \div 2000=3.75 → 3 full symbols and 0.75 or \cfrac{3}{4} of the fourth symbol.

\text { May }=6500 \div 2000=3.25 → 3 full symbols and 0.25 or \cfrac{1}{4} of the fourth symbol.

\text { June }=8500 \div 2000=4.25 → 4 full symbols and 0.25 or \cfrac{1}{4} of the fifth symbol.

Teaching tips for pictographs

• Make it a habit of creating a pictograph as a classroom, for common daily, weekly or monthly activities.
• Instead of giving students math worksheets to practice, provide authentic learning experiences for students where they can create their own pictographs with data they collected.
• Include projects that provide choice for students where they can choose the visual representation of data.
• Reinforce with students the importance of reading the key of pictographs so that they interpret the pictorial symbols and data correctly.
• Reinforce to students that pictographs are pictorial representations of numerical data. Similarly, bar graphs and pie charts are other ways to visually represent data.

Easy mistakes to make

• Thinking that a part of a symbol cannot be a whole number The use of part of a symbol does not mean that the actual value is fractional. For example, in the graph above, if the smiley face represents 4 people, then half of a smiley face would represent 2 people, which is NOT fractional, but a whole number.

Practice pictograph questions

1. Jamil records the number of sodas he drinks per day over one week.

He displays his results in the pictogram below.

Use the given data to determine how many sodas Jamil drank in total for the week?

The key shows that one symbol represents 1 soda. To find the total number of sodas Jamil drinks in the week, add up the amount of symbols in the pictograph.

3+5+2+1+3=14

2. A nursery school records the number of children that attend their after school play group over one week. The pictogram below shows their results.

Given that 8 children attended on Wednesday, determine the number of children who attended on Thursday.

The two rows that are important to focus on are Wednesday and Thursday.

There is no key provided with this pictograph, so you need to find the value of one smiley face so that you can find the number of children on Thursday.

Notice there are 4 smiley faces for Wednesday, which is equivalent to 8 children. To find out what 1 smiley face is equal to you can divide, 8 \div 4=2. \; 1 smiley face is equal to 2 children.

So, there are 2.5 smiley faces represented for Thursday, which means that there are 5 children in attendance for Wednesday. You can multiply, 2.5 \times 2=5

3. The table below shows the age of 5 children.

Represent this information in a pictogram. Use the key provided below.

Each candle represents 1 year so the number of candles for each row matches the age of the child. All the symbols are left aligned with the correct number in each row.

4. The number of different flavors of ice cream sold on one day is shown in the tally chart below.

Each symbol represents 2 ice creams, so we need to divide each frequency by 2 and then draw that number of ice creams in each row.

5. A delivery company is looking at how many pizzas they have delivered from 5 different companies in one evening.

As each symbol represents 8 deliveries and since the symbol is divided into 8 small pie pieces, one section of the symbol can represent 1 delivery.

Dividing each frequency by 8, you get the number of full symbols and the remainder represents how many more pieces of the symbols are needed.

6. The pictogram below shows the number of days of sunshine over 5 weeks. State the error made within this pictogram.

The symbols are not the same in weeks 2 and 4.

The frequencies are not in order from smallest to largest.

The symbols should be drawn on top of each other like a bar chart.

The number of days in week 3 is more than 7.

Week 3 has 4 suns. As each sun is worth 2 days, the number of days in week 3 is 4 \times 2=8 which is not possible.

4 - The Pictorial Representation of Data

Published online by Cambridge University Press:  03 February 2010

The last chapter has shown how tables can facilitate the reduction of the observer's raw data and material to a form which enables the reader to grasp the essential features portrayed. In this chapter a further stage in this reduction is dealt with in the construction of charts and diagrams, which enable the salient features of a set of data to be picked out and vividly portrayed so that the reader can spot, without detailed study of the individual figures, the features of particular interest. The primary consideration to be borne in mind in the construction of any chart or diagram is clarity, since a confused diagram is of little help and it is probably better to have no diagram at all, than one that is virtually impossible to understand without a great deal of effort on the part of the viewer. To achieve this standard it is essential to decide at the outset on the purpose of the diagram and to exclude all irrelevant matter from consideration.

Broadly speaking, different considerations are involved according to whether the data are concerned with qualitative or quantitative characters. In the former case the study is of some characteristic such as hair colouring, for which it is difficult to have a numerical scale, whereas for quantitative characters, such as the height of schoolboys, it is possible to have a continuous numerical scale whose accuracy is limited only by the inability of the measuring apparatus to record heights to an accuracy of less than about, say ⅛ in.

1.  Find the right icon. The power of pictorials is in their familiar shapes , so try to find icons that represent your categories. 

2. Avoid using very detailed icons. That way, the reader will be able to understand your chart at a glance. Try to think of the simplest picture that represents the data.

3. A void large data sets. Using a pictorial chart for large data sets will make it hard to count the values.

The origins of the pictorial chart can be traced back to the history of civilization. Early written symbols were based on pictographs (pictures that resemble what they signify) and ideograms (symbols which represent ideas). Ancient Sumerian , Egyptian , and Chinese civilizations began to adapt such symbols to represent concepts, developing them into logographic writing systems .  

The idea of the universal language of pictorials was best developed by an Austrian social scientist Otto Neurath and a German designer Gerd Arntz in the late 1920s. Together, they were the perfect fit to develop an ISOTYPE (International System Of Typographic Picture Education) – a set of 4,000 pictograms that could express almost anything.

Pictorial Representation Of Data: Bar Graph, Properties, Types & Examples

Collegedunia Team

Content Curator

Pictograph is a term for a visual or pictorial representation of data . For example, a bar graph allows data stakeholders to visually show a wide range of data, which not only improves understanding but also makes things easier for the merchant. The difference between realistic and logical visuals is a common one in graphical representations. Paintings, Photographs and drawings that are realistic have solid qualities & structures in common with the items they describe. A bar graph, often known as a bar chart, is the most basic visual data representation.

Pictorial Representation Using Bar Graph

[Click Here for Sample Questions]

A bar graph , also referred to as a bar chart, is a graph that displays data in the form of rectangular bars. The length of the bar is proportionate to the values it represents in this case. The bar graph can be formed both ways: vertical and horizontal orientation. The term “column bar graph” refers to a vertical bar graph. 

Bar graphs are used as comparative tools because they can display multiple groups of data on the same graph. The length of the rectangular bar refers to the value of each category. As these rectangular bars are proportional, the disparities between them may be seen much more easily than with words. Let’s look at bar graphs in more detail.

Assume your monthly salary is 15k, and You are free to spend this money in any way you see fit. You spend this money on Groceries, entertainment, electricity bill and all. What you observe is that the money appears to vanish very soon. So, you reluctantly create a bar chart to know about where you are actually spending your money so that you can balance your expenditure accordingly. However, you'll need data to make a bar chart. You should keep track of what you spend money on and how much you spend it on. After a month, you have the details of this months’ expenditure, and they look something like this.

The first thing to notice is how the information is organized. It is the first step in the process of making a bar graph. All the expenditures are all classed together. The same can be said for other things as well. When talking about a bar graph, it was noted that the values are represented by a rectangular bar, the length of which is proportional  to the data value. Another feature of a bar graph comes into play at this point. Let’s look at an example,

A uniform scale is required for a bar graph. The scale determines how the numerical data is converted into a rectangular representation. A bar graph is a visual depiction of numbers made up of bars of varying widths and lengths that are proportional to the number.

For example, if you use a 25 cm long rectangular bar to symbolize the money you spent on chocolate, the scale is 1 rupee equals one unit on the graph, i.e. one rupee equals one centimeter. However, it is evident that a large graph is required for this form of representation. The problem with scale is that we have complete control over it. So, instead of 25 cm, a rectangular bar of length 25 millimeters can be used to indicate the same number, and here the scale is 10 rupees equals one unit, i.e. 10 rupees equals one centimeter.

As clear information about the scale is critical for data interpretation, it is critical to state the scale of your graph on both the x-axis and the y-axis. Using the latter scale, one centimeter equals ten rupees. It’s vital to remember that all of the data groups in the bar graph have the same scale.

Properties of Bar Graph

Here are some important properties of Bar Graph: 

• Each bar or column in a bar graph must have the same width. 
• All rectangular bars must have equal space between them.
• The base of the bars is common in a bar graph. 
• The height of the bars proportionally represents the data in the bar graph. 
• Depending on the data, the bars can be drawn horizontally or vertically.

Types of Bar Graphs

A bar graph is used to show data in a graphical representation. Here are some different types of Bar graphs:

• Vertical bar graph

Vertical bar graphs are graphs or charts in which the given data is shown vertically in a graph or chart with the use of rectangular bars that display the data measure. The y-axis indicates the value of the height of the rectangular bars, which reflects the quantity of the variables stated on the x-axis, and the x-axis shows the vertically drawn rectangular bars.

• Horizontal bar graph

Horizontal bar graphs are graphs in which the provided data is displayed horizontally by rectangular bars that display the data measure. The variables or classifications of the data must be written, and then rectangular bars must be constructed horizontally on the y-axis, with the length of the bars equivalent to the values of the various variables present in the data on the x-axis.

• Stacked Bar Graph

The composite bar graph is another name for the stacked bar graph. It separates the entire bar into sections. Each segment of a bar is represented by a different colour to make it easier to distinguish between the many categories. It necessitates appropriate labelling to distinguish the various portions of the bar. In a stacked bar graph, each rectangular bar represents the entire graph, and each segment in the rectangular bar represents the various components of the entire graph. It can be displayed horizontally or vertically.

• Grouped Bar Graph

The clustered bar graph is another name for the grouped bar graph. It's used to represent the discrete value of two or more categorical data sets. Rectangular bars are clustered by position for levels of one categorical variable, with the secondary category level in each group shown in the same colour. It can be displayed in both vertical and horizontal orientations.

Pictorial Representation of Data using Vertical Bar Graph

Vertical bar graphs are frequent visual representations that employ vertical bars to communicate data. The categories are represented by the horizontal axis, while the data for each category is represented by the vertical bars. The x-axis is the horizontal axis, while the y-axis is the vertical axis.

Vertical bar graphs can also be used to depict a sequence of data and how it changes over time. All of the vertical bars run from the x-bottom axis to its top.

Pictorial Representation of Data Using Horizontal Bar graph

The data is represented in the horizontal bar graph by bars that are parallel to the x-axis. The types are defined on the y-axis, and the data is represented by horizontal bars. The horizontal graph's bars run from left to right along the x-axis.

For example,  A class teacher of Grade 5 made a note of the students who passed in every subject in the class. She represented the data in the form of a horizontal bar graph to know the passing students in every subject.

You've seen how the bar graph of your first week's expenses looks. Assume you keep track of where you spent your money for a while longer. You discover that your expenses for week two differ slightly from those for week one. The second-week expenses are as follows:

They can all be plotted on the same bar graph because they are all part of the same group. Remember that the scale is the same for all the data in the graph. Rather than charting them independently, you can compare the changes over a longer time span or across a wider range of data by grouping them together. Now that we've plotted everything together, we'll be able to see the differences in weekly spending.

This process also allows you to control your spending because you now know where your money is going. This allows you to determine whether your expenses are necessary.

Things to remember

• A bar graph, often referred as a bar chart, is a graph that displays data in the form of rectangular bars. 
• A bar graph is used to show data in a graphical representation. 
• For pictorial representation, there are 3 kinds of bar graphs to choose from: Vertical bar graph, horizontal bar graph and Double bar graph. 
• The bar graph can be formed both ways: vertical and horizontal orientation. The term “column bar graph” refers to a vertical bar graph. 
• Bar graphs are used as comparative tools because they can display multiple groups of data on the same graph. 

Sample Questions

Ans. We can plainly see from the graph above that the fewest number of cakes were prepared on Tuesday because Tuesday is the smallest bar. Following this bar, we can see that 10 cakes were produced on this particular day.

• The data represented by the bar graph is as follows:

• The total number of cars made in the fourth week = 300, as can be seen in the graph above.

As a result, the total number of cars produced during the fourth week was 300.

Ans.  The quantity of shirts sold on Thursday is 3535 units, as seen in the bar graph.

Ans.  The minimum mark for Social Studies is 4040, as shown in the bar graph.

As a result, Ajay received the lowest possible grade in Social Studies.

Ans. A bar graph is a visual representation of data that uses vertical or horizontal bars of consistent width to represent data. They can be drawn on the horizontal axis (say, the X-axis) with equal spacing between them to represent the variable. The variable’s values are displayed on the vertical axis (say, the Y-axis), and the heights of the bars are determined by the variable’s values.

As a result, rather than playing, most students prefer to read storybooks.

Ans. It is obvious that wheat output in 1998 was at a minimum, which was 15.

Ans.  The data can be represented by the following double bar graph:

Ques. Differentiate between a bar graph and a histogram. (3 Marks)

Ans. A bar graph and a histogram are differentiated as follows:

Ans. The variable shown on the X-axis in the given bar graph is 'Months of Birth,' while the value of the variable plotted on the Y-axis is 'Number of Students.'

By looking at the graph, one can see that there are four individuals born in November.

By looking at the graph, it can be seen that the most individuals were born in August.

Guide To What Is The Pictorial Representation Of Worksheet Data

Introduction.

When dealing with a large amount of data, it can be overwhelming to make sense of it all. This is where the pictorial representation of worksheet data comes into play. It is a visual way of representing data using graphs, charts, and other visual elements. This method helps in presenting complex data in a simplified and easy-to-understand format, making it easier for anyone to analyze and interpret the information.

Using pictorial representation in data analysis is crucial as it allows for quick and easy identification of patterns, trends, and outliers at a glance. This visual aid helps in making informed decisions and presenting findings effectively to stakeholders.

Key Takeaways

• Pictorial representation of worksheet data uses graphs, charts, and visual elements to simplify complex data and make it easier to analyze.
• Using pictorial representation allows for quick identification of patterns, trends, and outliers, aiding in making informed decisions.
• When choosing the right pictorial representation, consider the type of data, the message you want to convey, and the audience's familiarity with different types of graphs.
• Best practices for creating pictorial representation include using appropriate scaling, labeling axes, using consistent colors and symbols, and avoiding data distortion.
• Benefits of using pictorial representation include making data easier to understand, highlighting trends and patterns, simplifying complex information, and engaging the audience.

Types of Pictorial Representation

When it comes to representing worksheet data in a visual format, there are several types of pictorial representations to choose from. Each type has its own unique characteristics and is best suited for displaying specific types of data. Let's take a closer look at some of the most commonly used types of pictorial representation:

Bar graphs are one of the most popular and widely used forms of pictorial representation. They are ideal for comparing the values of different categories or groups. The length of the bars represents the value of each category, making it easy to visualize and compare the data.

Pie charts are circular graphs that are divided into slices to represent the proportion of each category within the data set. They are useful for illustrating the breakdown of a whole into its constituent parts and are particularly effective for showing percentages.

• Line graphs

Line graphs are used to display data points connected by straight lines, making it easy to see trends and patterns over time. They are especially useful for showing changes and fluctuations in data over a continuous period.

• Scatter plots

Scatter plots are used to display the relationship between two variables. Each data point is represented by a dot on the graph, and the pattern of the dots can reveal the nature of the relationship between the variables, such as correlation or clustering.

How to Choose the Right Pictorial Representation

When it comes to representing worksheet data visually, selecting the right pictorial representation is essential for effectively communicating information. Here are some key factors to consider when making this decision:

A. Consider the type of data being represented

• 1. Numerical data: If your data consists of numerical values, bar graphs, line graphs, and pie charts are commonly used to depict this type of information. Bar graphs are ideal for comparing values across different categories, while line graphs show trends over time. Pie charts can be used to illustrate the proportion of each category within a whole.
• 2. Categorical data: When dealing with categorical data, bar graphs, pie charts, and stacked bar graphs can effectively showcase this type of information. Bar graphs and stacked bar graphs can compare values within categories, while pie charts display the distribution of each category.
• 3. Relationships between variables: For showing relationships between variables, scatter plots and line graphs are often utilized. These types of graphs can reveal patterns and correlations within the data.

B. Determine the message you want to convey

• 1. Trends: If the goal is to highlight trends or patterns within the data, a line graph or scatter plot may be the most suitable choice. These representations can effectively showcase changes over time or relationships between variables.
• 2. Comparisons: When the objective is to compare different categories or values, bar graphs and pie charts can clearly illustrate these comparisons. Stacked bar graphs are particularly useful for simultaneously comparing subcategories within larger categories.
• 3. Distribution: If you need to display the distribution of categorical data, a pie chart or stacked bar graph can visually represent the proportions of each category within the dataset.

C. Assess the audience's familiarity with different types of graphs

• 1. General audience: If the intended audience is not familiar with complex data representations, it may be best to opt for simpler graphs such as bar graphs and pie charts. These are commonly understood and can effectively convey the information to a broad audience.
• 2. Data-savvy audience: For an audience well-versed in data analysis, more advanced representations like scatter plots and stacked bar graphs may be appropriate. These individuals can interpret and derive insights from more intricate visualizations.

Best Practices for Creating Pictorial Representation

When creating pictorial representations of worksheet data, it's important to follow best practices to ensure that the visualizations accurately and effectively communicate the information. The following are some key best practices to keep in mind:

• Use appropriate scaling

It's important to choose the right scale for your pictorial representation to ensure that the data is accurately represented. Be mindful of the range of the data and choose a scale that effectively captures the variations without distorting the overall picture.

• Label axes and provide a clear title

Labeling the axes and providing a clear title for your pictorial representation is essential for helping the audience understand the context and meaning of the data. Make sure the labels and title are clear, concise, and informative.

• Use consistent colors and symbols

Consistency in the use of colors and symbols in your pictorial representation is crucial for clarity and coherence. Choose a color palette and set of symbols that are easily distinguishable and use them consistently throughout the visualization.

• Avoid distorting the data

It's important to avoid distorting the data in your pictorial representation. Be cautious of various visual techniques such as skewed scales, exaggerated proportions, and manipulated axes that can misrepresent the data.

Tools for Creating Pictorial Representation

When it comes to visualizing data from a worksheet, there are several tools available that can help you create pictorial representations. Here are some of the most popular ones:

Excel is a widely used spreadsheet software that offers various chart and graph options to visually represent data. You can easily create bar graphs, pie charts, line graphs, and more to effectively showcase your worksheet data.

Google Sheets also provides a range of chart types to visually depict your data. With its intuitive interface and built-in chart tools, you can quickly create appealing visual representations of your worksheet data.

Tableau is a powerful data visualization tool that allows you to create interactive and dynamic visualizations. It offers advanced features for creating dashboards, maps, and other complex visual representations of worksheet data.

Infogram is a user-friendly tool for creating infographics, charts, and maps. It provides a range of templates and customization options to easily transform your worksheet data into engaging visual content.

Benefits of Using Pictorial Representation

When it comes to presenting worksheet data, using pictorial representation can offer several benefits that can enhance understanding, highlight key trends, simplify complex information, and engage the audience.

Pictorial representation such as graphs, charts, and diagrams can make it easier for individuals to comprehend the data presented. Visualizing the data can help in clarifying the information and making it more accessible.

By using visual representations, it becomes easier to identify trends and patterns within the data. Whether it's a fluctuation in sales over time or a correlation between different variables, pictorial representation can make these insights more apparent.

For datasets that contain complex information, using visuals can simplify the presentation of the data. Instead of overwhelming the audience with raw numbers and figures, creating a visual representation can simplify the message and make it more digestible.

Visuals are inherently more engaging than plain text or tables of data. Pictorial representation can capture the audience's attention and make the information more memorable. This can be particularly effective when presenting to a diverse audience with varying levels of data literacy.

As we wrap up this discussion on the pictorial representation of worksheet data, it's important to emphasize the significance of using graphs and charts to visually represent data. Not only do they make complex data more understandable, but they also facilitate quick and easy analysis. I encourage all readers to incorporate various types of graphs, such as bar graphs, pie charts, and line graphs, in their data analysis to gain deeper insights into their data.

Pictorial Representation

Some basic ideas of pictorial representation or pictograph, often related types of symbols or pictures are used to represent a specific number of objects.

For example, a symbol may represent 1 or 10 or 100 or 1000 or any other number of related objects. The symbol/picture used is very simple, clear and self explanatory. The quantity that each symbol represents is indicated clearly in the representation, i.e. the scale is mentioned clearly.

1.  Examples of objects whose pictures or symbols are used are: different kinds of animals like birds, insects, men, women, boys, girls, fruits like mangoes, grapes, oranges, apples, trees, cars, scooters, bicycles, plants, etc.

2.  The symbol or pictures may be colored. So such colors should be used which are very common, like red, blue, green, yellow, etc.

3.  Only the pictures of common fruits are used such as banana, apples, guava, orange, grapes, mangoes, etc.

4. Sometimes the names of the month of a year, or the days of a week need to be mentioned. The names of the months and days may be written vertically and in front of each we may write the roll numbers of the students according to their birthday and birth month. This way we may show the number of students who are born in the month or day concerned.

5. Sometimes, data on yearly production such as the yearly production of wheat or rice in a state, of steel in a factory, etc., may have to be represented. Thus, we must be acquainted with the numbers used to describe the years 2007, 2008, 2009, 2010, 2011, 2012, etc.

So, pictures of different objects are used as a symbol to give information regarding mathematical data.

In short, the information presented through pictures or symbol of different objects is called pictorial representation of data. The pictures of different objects are used to represent different information, so such pictorial data are called pictographs .

Pictographs

The students of Class 2 were asked to choose their favourite colour from the colours of the rainbow. The teacher then collected their response and made a chart to show the information.

My Colour of the Rainbow

In the chart, each smiling face represents a student. Such a chart that displays information using pictures is known as a pictograph .

Let us see what information we can gather from this pictograph.

Some information can be directly read from the pictograph.

1. The pictograph is titled 'My colour of the rainbow' and it shows us the favourite colour chosen by the students of Class 2.

2. Violet is the favourite colour of 8 students.

3. Indigo is the favourite colour of 0 students.

4. Blue is the favourite colour of 9 students. 5. Green is the favourite colour of 7 students.

6. Yellow is the favourite colour of 9 students.

7. Orange is the favourite colour of 5 students.

8. Red is the favourite colour of 12 students.

Some information can be understood after studying the pictograph.

1. Red is the most popular colour choice of the students.

2. Indigo is the least popular colour choice of the students.

3. An equal number of students chose yellow and blue as their favourite colours.

4. Between violet, green and orange, violet is the most popular colour.

5. Three more students chose violet than those who chose orange as their favourite colour.

Sometimes, when the scores are high, it is not possible to draw so many pictures in a pictograph. In such pictographs one picture can be made to represent a score of more than one. This can be explained better using the example that follows.

Reading Pictograph:

1. Five friends participated in an apple-picking competition. The result of the competition held in an orchard is shown in the pictograph below. Study the pictograph and answer the questions that follow.

Apple Picking Score

(i) Who picked the most number of apples?

Answer: The most number of apple pictures can be seen in Amelia's column.  Thus, Amelia picked the most number of apples.

(ii) Who picked the least number of apples?

Answer: The least number of apple pictures can be seen in Giovanna's column. Thus, Giovanna picked the least number of apples.

(ii) Who picked an equal number of apples?

Answer: An equal number of apple pictures can be seen in Katherine and Amara's columns. Thus, Katherine and Amara picked an equal number of apples.

(iv) How many apples did Yasmin pick?

Answer: Five apple pictures can be seen in Yasmin 's column. It is given in the pictograph that each apple picture stands for 10 apples picked.

Thus, Yasmin picked 5 × 10 = 50 apples.

(v) How many more apples did Katherine pick than Giovanna ?

Answer: Compared to the two apple pictures in Giovanna 's column, Katherine has three or one more picture. Thus, Katherine picked 1 × 10 = 10 more apples than Giovanna .

(vi) How many apples did Amelia pick?

Answer: Amelia picked 6 × 10 = 60 apples.

(vii) How many apples were picked in all by the five friends?

Answer: There are a total of 19 apple pictures against all the five friends. Thus, a total of 19 × 10 = 190 apples got picked by all the five friends.

(viii) How many apples did Amara and Giovanna pick together?

Answer: Amara picked 3 × 10 = 30 apples while Giovanna picked 2 × 10 = 20 apples. Together they picked 30 + 20 = 50 apples.

2. In the month of March Seema bought different types of fruits every week. Read the I pictograph and answer:

(i) Which week did she buy maximum fruits?

(ii) Which week did she buy 5 fruits?

(iii) How many weeks did she buy fruit?

(iv) Which week did she buy least fruits?

3. Read the pictograph given below and answer the question. (Here 1 picture represents 5 animals.)

(i) What is the total number of animals?

(ii) Which kind of animal is least in number?

(iii) How many tigers are there?

(iv) How many herbivorous animals are there?

4.  Make a pictograph to show the number of star stickers owned by five

It would be very hard to show so many stickers against each friend. So, we can show one picture for every 10 stickers owned.

Star Stickers Owned by Five Friends

5. The mode of transport availed by the students of a preparatory school is put up in a chart on the wall as a pictograph. Study it and answer the questions that follow.

Mode of Transport Availed by the Students

(i) What is the title of this pictograph? (ii) What does one smiling face represent?

(iii) Which is the most popular mode of transport for the students?

(iv) Which is the least popular mode of transport for the students?

(v) How many students travel by private cars?

(vi) How many students travel by a mode of transport that gives out no smoke and consumes no fuel?

(vii) How many students travel to school by a mode of transport that has an engine and consumes fuel?

6. Standing at the bus stop waiting for his school bus, Robert counted all the vehicles that went past him in 10 minutes. He recorded his observations in the following pictograph. Answer the questions that follow .

Vehicles that Went Past in 10 Minutes

(i) How many different kinds of vehicles went past Robert?

(ii) Out of all the vehicles that went past Robert, which was the most in number?

(iii) Out of all the vehicles that went past Robert, which was the least in number?

(iv) How many buses went past Robert in 10 minutes?

(v) How many cars and bicycles went past Robert ?

(vi) Which were most in number - two wheelers (motorcycles and bicycles), three wheelers (autorickshaws) or four wheelers (cars and buses)?

(vii) How many more cars than bicycles went past Robert?

(viii) How many vehicles in all went past Robert in 10 minutes?

Pictograph in Statistics

Pictograph in Statistics: A pictograph is a visual representation of data employing images or symbols. It depicts the frequency or occurrence of data by utilizing relevant symbols or images. Pictographs provide a straightforward method to convey statistical information.

In statistics , we use the concept of data handling to deal with large data sets. The methods of data handling include bar graphs, histograms, pie charts, etc. Pictograph is essential for students of class 6 and class 7 to learn data handling.

In this article, we’ll learn about what are pictographs in maths, pictograph definitions, how to make a pictograph, and how to read a pictograph. We will also see examples of pictographs with explanations and also have some pictograph questions to practice on their own.

Pictograph meaning in maths, parts of pictograph, how to make a pictograph, how to read a pictograph, pictograph example, advantages of pictograph, disadvantages of pictograph, pictograph solved examples, pictograph questions for class 3 & 4.

A pictograph is a way to show information using pictures and symbols instead of just numbers. It helps make data easier to understand compared to looking at the plain numbers. The scaled-up image represents the magnitude of the data point.

A pictograph is defined as a method of representing a dataset by a symbol or picture for a word or phrase.

A pictograph is made of using two words that are (picto from picture) and graph which means that organizing data in the form of pictures and graphs is known as a pictograph.

Parts of a pictograph include the following:

• Title: It is a title that describes what the pictograph is of.
• Icon or Symbol: This visual representation represents individual data points or categories.
• Data values: It represents the quantity of each data point.
• Labels: It provides more details about the data points.
• Color (optional): It adds more meaning or readability to the pictograph.

To create a pictograph, follow the steps listed below:

• Understand the data: The first and foremost step to creating a pictograph is to understand the data i.e. the type of data given to create a pictograph.
• Choose icons or symbols: To create your pictograph you need to select an icon or image by which you are going to represent the data.
• Provide a scaling factor: You need to provide a scaling factor that represents the quantity or value of the icon.
• Use colours: This is the optional step that is used to enhance your pictograph.
• Present your Pictograph: After performing the above steps you can present it as a presentation.

To read a pictograph you need to follow the below given steps:

• Identify the data points: Identify the data points as they are labelled by using the meaning of images or icons.
• Count the icons or symbols: Count the number of icons or symbols associated with it. The number of icons represents the value of that data point. If there is a scaling factor, keep that in mind when counting.
• Interpret the data: Use the information you gathered in step 3 to interpret the data. For instance, if you see three apple images in a category called “Apples,” and the key says that each icon symbolizes five apples, you may figure out that there are 3 x 5 = 15 apples in that category.
• Conclude: Now conclude from the above information.

In the above two headings we have learnt steps how to read and create pictograph, now we will learn to create and read a pictograph using an example.

Suppose you want to represent the number of books four students read in a month using a pictograph. The data for the same is given below:

• To create a pictograph we need to understand the data first that is the type of data as in our table some students are there with some books.
• Now, we will choose an icon to make a pictograph. After choosing an icon we will provide a scaling factor which will be 2 in the given example.
• Now, we will present our pictograph

To read the pictograph, identify the icon which is a book in this case, and then look for the scaling factor and then based on the scaling factor count the icons for every student and then find the value by multiplying the number of icons with the scaling factor(interpreting the data). Now find conclusions.

Now since each picture of book represent two books and the pictograph shows student A has two book pictures hence, student A has in total 2 × 2 = 4 books. Similarly Student B has 4 × 2 = 8 books, Student C has 3 × 2 = 6 books and Student D has 4 × 2 = 8 books.

Since, the pictograph is one of the easiest way to represent a data. It has got several advantages. These advantages are discussed below:

• They are very easy to understand as they use only symbols to represent the data.
• Pictographs reduce complex data by representing it visually.
• They gain more attention from people as people feel it is complex to understand the raw data as compared to pictographs.
• Pictograph makes it very easy for the user to understand the raw data and draw insights from it.

A pictograph although a very easy and convenient tool to represent data but it has also got some limitations especially in the case of lengthy and complex datasets. Let’s learn the different disadvantages of Pictograph.

• Limited data is represented on pictographs. It is not suitable for large datasets.
• It can be complex to choose a scale for our pictograph.
• Pictographs may not capture all the data details, including outliers or extreme values.
• Pictographs often lack context, which means viewers may need additional information or labels to fully understand the data being presented.

Let us understand the concept with the help of an example.

Example 1: Draw a line graph for the given data.

Here the scaling factor is 5

Example 2: Draw a pictograph for the given data.

Here scaling factor will be 5 i.e. one picture of scaling factor will represent 5 ice creams.

Example 3: Draw a pictograph for the given data.

Here scaling factor will be 10.

Example 4: Draw a pictograph for the given data.

Here scaling factor is 1.

Q1: Draw a pictograph based on fruit consumption.

Q2: Draw a pictograph based on transportation choices by people.

Q3: Draw a pictograph for the following data.

Q4: Draw a pictograph for the following data.

FAQs about creating a pictograph

What is a pictograph .

A pictograph is a pictorial representation of data that uses icons, images, or symbols related to the central topic. A key is often included in the chart to indicate what word or numerical data group each icon represents.

The size of your icons must be the same except when you need to show a fraction relative to the amount per key.

Take a look at the pictograph example below. While the numerical values are bold and clear, you appreciate the data more because of the supplemental icons. It emphasizes the point of the pictograph.

This is an excellent design for the type of advocacy where you want to highlight statistics. Or you can use it in a pitch deck to show how many students are using your product.

Another good pictograph design can be found below. As we all know, infographics have been an effective tool to inform and educate the market. This pictograph represents how many children are using social media channels as well as their usage behavior.

And by using pictographs, you get to send your message across clearly. In this specific example, the infographic uses both icons and real photos, making the data easy to understand.

Best Venngage pictograph examples

Venngage has several templates for pictographs and infographics. We’ve shared a few examples, but here are a few more.

Population growth infographic example

Using different colors for your pictographs is a great strategy if you want to make your design interesting. This can be seen in the picture graph template below.

Apart from making your chart visually appealing, it makes your data stand out. Numbers become clearer and your audience is better able to understand the information right away. 

Kubler Ross change management example 

If you want to add more information about your pictograph, you can see how the change management communication template below is organized for inspiration.

The categories in the pictograph are straightforward. However, before you present this information to management, you will want to give more details, especially because the subject is related to your employees.

In other words, when you create pictographs, always consider your audience. Ask yourself, what do they need to know and what details can improve your pictogram?

How NPS works infographic example

You can also get creative with your pictographs similar to what you can get from our next example. Instead of using similar graphics, this template uses a variety of styles to represent different categories.

You can follow this style for your own pictogram design. Your audience will be more engaged and interested if your pictograph is unique.

Now that you know the parts of a pictograph, how can you create one:

• Collect the data – Identify the data for the different categories to create the best chart . From there, create a list or table so you can easily plot it into a pictogram once you have all the other elements.
• Choose a symbol – Think about the most relevant icons or symbols you can use to depict the given data in your pictograph. If you are talking about time, you can use a watch or even an hourglass.
• Include the key – Assign a numerical value per icon. For example, an hourglass could represent five hours. Make sure to include the key in your graph so that your audience will be able to translate your data properly. 
• Lay out your pictograph – Create two columns where you can place your categories and data. Add the icons based on your key.
• Review the design – Check all your labels and review to make sure you haven’t missed anything from your report. You can also ask the opinion of others so you can improve your design. 

If you don’t want to start from scratch or aren’t sure of your design abilities, use Venngage’s templates to depict your pictograph. With over a thousand free templates, you can depict any type of data.

With Venngage for business , you can add your brand kit to all designs with a single click. Use the My Brand Kit feature to automatically import your logo, colors, and fonts.

Most of the examples of pictographs in this post are contained within infographics. However, for a standard pictograph, these are the essential elements that you need to include:

• Graph title 
• Categories 

You can see these elements in action in the following pictograph. Note each symbol is the same size and the difference in numbers is only depicted through a change in color hue.

The above pictograph shows how many students have access to phones. These statistics could have been shown as raw numbers, but a pictograph can visualize numbers so the audience understands them at a glance.

What is the importance of using pictographs? 

Pictographs are commonly used in mathematics and in data handling. This type of pictorial representation is ideal for early learners because it’s visually appealing and easier to understand compared to other types of charts .

But pictographs have plenty of uses for the corporate world. They can be used in business settings where large amounts of data need to be presented in a by-the-numbers infographic .

Nonprofit organizations can benefit from using pictographs, like in the below pictogram example.

To highlight the percentage of refugee children who are orphaned, the template uses a broken heart icon that. This strengthens the message of the infographic. 

Here’s a statistical infographic on a similar central topic that has also used pictographs. 

The template uses immediately recognizable and relevant icons for wastewater and highlights the given data by adjusting the transparency. This is a great technique if you want your pictograph to follow a minimalist approach while still breaking down complex data.

Visualizing data is easy with Venngage’s import data function. Import your information from a Google sheet or CSV into the Venngage editor and the charts automatically populate the data.

Are pictographs and pictograms the same? 

Many people confuse pictographs and pictograms . They are actually the same. However, do not confuse them with  ideograms that use geometric shapes and lines to represent ideas.

Pictographs and pictograms use pictures, icons, and symbols to depict a topic. For example, you can use the sun to indicate summer, clouds for a windy day, flame for fire, ice cream for desserts, or waves for oceans.

The infographic below uses icons that are universally acknowledged as figures for males and females. 

Ideograms are more complex to understand than the above table because they represent abstract ideas.

What are the common mistakes in pictograph designs?

Creating a pictograph can be exciting. But that’s also the reason why most people make mistakes with their designs. These are the errors to avoid while making a pictogram. 

First, don’t forget to add the title for your pictograph. No matter how good your charts and symbols are, not having a title can confuse your audience. Do not expect that people will understand your graph with that. Highlight your title and use larger fonts. 

Since we’re talking about text, always check that you have labeled your graph properly. This includes the categories and the definitions in your key. 

Another mistake is using complex icons. The goal is to design a pictogram that everyone can understand at a glance. Use symbols and icons that are universally known. 

If you aren’t sure about creating pictographs, using an online design platform like Venngage will make the process easier.

How do you use a pictograph maker? 

In today’s digital age, we all need to be efficient. If you can automate tasks, you can get more work done. The same goes for creating graphs .

It’s fine if you aren’t comfortable designing infographics or pictograms. With the Venngage chart maker, creating a pictograph is a breeze.

Sign-up is free and you can start creating immediately. Choose a template, edit the data and swap out icons. It takes little time to work with the intuitive editor before your design is complete.

Use pictogram design to represent data in a visually-appealing way

The examples above prove that pictorial representation can be a powerful tool for sharing complex data with a wider audience.

With Venngage’s simple design solution, you can create a memorable pictogram for marketing and business materials and make an impact on your customers.

A pie chart is a pictorial representation of data in the form of a circular chart or pie where the slices of the pie show the size of the data. A list of numerical variables along with categorical variables is needed to represent data in the form of a pie chart. The arc length of each slice and consequently the area and central angle it forms in a pie chart is proportional to the quantity it represents.

What is Pie Chart?

A pie chart is a type of a chart that visually displays data in a circular graph. It is one of the most commonly used graphs to represent data using the attributes of circles , spheres , and angular data to represent real-world information. The shape of a pie chart is circular where the pie represents the whole data and the slice out of the pie represents the parts of the data and records it discretely.

Pie Chart Definition

A pie chart is a type of graph that records data in a circular manner that is further divided into sectors for representing the data of that particular part out of the whole part. Each of these sectors or slices represents the proportionate part of the whole. Pie charts, also commonly known as pie diagrams help in interpreting and representing the data more clearly. It is also used to compare the given data.

Pie Chart Example

Let us look at the following example of the following pie chart that represents the ingredients used to prepare a butter cake.

Example: The whole pie represents a value of 100. It is divided into 10 slices or sectors. The various colors represent the ingredients used to prepare the cake. What would be the exact quantity of each of the ingredients represented in specific colors in the following pie chart?

Solution: As we can see, the pie is divided into 10 slices or sectors. To calculate the exact amount of ingredients that are added to the cake, we divide the whole sector's value, i.e., 100 by the number of sectors. So, 100 ÷ 10 = 10. Hence, looking at the color divisions made in the pie chart we can conclude that:

Pie Chart Formula

We know that the total value of the pie is always 100%. It is also known that a circle subtends an angle of 360°. Hence, the total of all the data is equal to 360°. Based on these, there are two main formulas used in pie charts:

• To calculate the percentage of the given data, we use the formula: (Frequency ÷ Total Frequency) × 100
• To convert the data into degrees we use the formula: (Given Data ÷ Total value of Data) × 360°

We can work out the percentage for a given pie chart using the steps given below,

• Categorize the given data and calculate the total
• Divide the different categories
• Convert the data into percentages
• Calculate the degrees

Let us understand the above steps using an example.

Example: Observe the following pie chart that represents the money spent by Ana at the funfair. The indicated color shows the amount spent on each category. The total value of the data is 20 and the amount spent on each category is interpreted as follows:

• Ice Cream - 4
• Toffees - 4
• Popcorn - 2

To convert this into pie chart percentage, we apply the formula: (Frequency ÷ Total Frequency) × 100

Let us convert the above data into a percentage :

Amount spent on rides: (10/20)× 100 = 50%

Amount spent on toffees: (4/20)× 100 = 20%

Amount spent on popcorn: (2/20)× 100 = 10%

Amount spent on ice-cream: (4/20)× 100 = 20%

Observe the following pie chart that recommends a low-carb diet on a day.

We measure the angles of each slice. We get that Protein measures 180° , Carb measures 108°, and Fats measures 72°

To find the percentage, we divide each angle by 360 and multiply it by 100.

Protein = (180/360) × 100 = 50%

Carb = (108/360) × 100 = 30%

Fats = (72/360) × 100 = 20%

Uses of Pie Chart

Whenever some data has to be represented visually as a fractional part of a whole, we use pie charts. It is used to compare the data and see why one is smaller/greater than the other. Therefore, when we are dealing with a limited number of buckets and discrete data sets, it’s better to use a pie chart. Listed below are a few uses of a pie chart:

• In a business, it is used to compare the growth areas such as profit and loss.
• In school, pie charts are used to show the time allotted to each section, the grades of students in a form of percentages, etc.
• Pie charts are used in comparing the relative size of data of people owning the same vehicles, similar houses, etc.
• They are used to represent the marketing and sales data for the comparison of brands.

Steps to Construct Pie Chart

We use the following steps to construct a pie chart and using the above-mentioned formulas, we can calculate the data.

• Step 1: Write all the data into a table and add up all the values to get a total.
• Step 2: To find the values in the form of a percentage divide each value by the total and multiply by 100.
• Step 3: To find how many degrees for each pie sector we need, we take a full circle of 360° and use the formula: (Frequency/Total Frequency) × 360°
• Step 4: Once all the degrees for creating a pie chart are calculated, draw a circle (pie chart) using the calculated measurements with the help of a protractor.

Example: Construct a pie chart to visually display the favorite fruits of the students in a class based on the given data: Mango - 45; Orange - 30; Plum - 15; Pineapple - 30; Melon - 30

Step 1: Create a table with the values and get the total.

Step 2: Find the percentage of each value:

Mango = (45/150) × 100 = 30%

Orange = (30/150) × 100 = 20%

Plum = (15/150) × 100 = 10%

Pineapple = (30/150) × 100 = 20%

Melon = (30/150) × 100 = 20%

Step 3: Finding the degree of each pie sector using the formula: (Given data/Total Value of data) × 360°

With all the above degrees, with the help of a protractor draw a pie chart. Thus, the pie chart looks like this:

Interpreting Pie Chart

To read or interpret a pie chart, we see if the given chart is given in percentages or without any value. If it is given in percentages, the conversion is made accordingly and interpreted accordingly. Let us look at an example to understand this better.

Example: The pie chart shown below shows the percentages of types of transportation used by 500 students to come to school. With this given information, answer the following questions: a) How many students come to school by bicycle? b) How many students do not walk to school? c) How many students come to school by bus and car?

a) The students who come by bicycle = 25%; (25/100) × 500 = 25 × 5 = 125

b) The students who do not walk to school - We need to add the values of all the remaining means, i.e., bus + car + bicycle = 26 + 32 + 25 = 83

Hence, (83/100) × 500 = 83 × 5 = 415 students do not walk to school.

c) The students who come by bus and car [(32 + 26)/100] × 500 = 58 × 5 = 290

Pie Chart Advantages

Given below are the advantages to a pie chart which are the reasons for the widespread application of pie charts in different fields.

• A pie chart is a simple and easy-to-understand method to represent the data visually as a fractional part of a whole.
• It provides an effective communication tool visually simpler than other types of graphs.
• Pie chart helps in data comparison for the audience at a glance to give an immediate analysis or to quickly understand information due to widespread use in business and the media.

Pie Chart Disadvantages

There are few demerits in pie charts. These are as given below,

• A pie chart cannot show more than a few values without separating the visual encoding from the data they represent, that is they are not very effective when the number of values in a data set increases.
• It does not easily reveal exact values in the data set.
• To show the changes in the data, many pie charts may be needed. It, therefore, fails to explain the causes, effects, or patterns.

Pie Chart Examples

Example 1: The following chart shows the various activities done by Diana in a week.

a) Calculate the central angle subtended at sleeping.

b) Find the portion of time spent by Diana at school.

c) Find the central angle subtended in playing.

a) Time spent in sleeping = 34%; (34/100) × 360 = 122.4°. Therefore, the central angle subtended at sleeping = 122.4°

b) Time spent at school = 25%; 25/100 = 1/4. Therefore, she spends 1/4th of her time in school.

c) Time spent on playing = 8%; (8/100) × 360 = 28.8°. Therefore, the central angle subtended at playing = 28.8°

Example 2: The pie chart shows the favorite subjects of students in a class. Using the information given in the pie chart, find the percentage of students who chose English.

Let's first determine the percentage of students who chose English by looking at the pie chart.

We know that 144° + 36° + 72° + 108°= 360°

The percentage of students who chose English: (72/360) × 100 = 20

Therefore, the percentage of students who chose English = 20%

Example 3: A pie chart is divided into 3 parts with the angles measuring as x, 4x, and 5x respectively. Find the value of x in degrees.

We know, the sum of all angles in a pie chart would give 360º as result. ⇒ x + 4x + 5x = 360º ⇒ 10 x = 360º ⇒ x = 360º/10 ⇒ x = 36º Therefore, the value of x is 36º.

Pictograph Examples

Pictograph and interpretation of a pictograph.

A pictograph is a way to represent data using images. Each image in the pictograph represents a certain number of things. In other words, a pictograph uses pictures and symbols to convey information about the provided data. Pictographs should be used very carefully and it is very comfortable to use, but sometimes they may lead to misinterpretation of data as well. Whenever pictographs are drawn, they should look visually correct as most of the times the data is interpreted visually. Different  pictorial representation of data such as bar graph, line graph, pie charts and so on are available to easily interpret the data.  In this article, let us discuss the definition of pictograph, how to make a pictograph, its advantages with many solved examples.

Table of Contents:

How to Make a Pictograph?

Pictograph definition.

The pictograph is a method to represent the data using images. Each image in the pictograph represents certain things. In other words, pictographs define the frequency of the data using images or symbols, which are relevant to the data. The pictograph is extremely easy to understand, and it is one of the simplest ways to represent the statistical data. In the pictograph, we use a key , which denotes the value of the symbol. While using symbols or images, all the symbols should be of the same size.

Advantages of Using Pictographs

Some of the important advantages of using Pictographs are as follows:

• Pictographs are used to express large information in a simple manner.
• It is easy to read, as all the information is provided at one glance.
• It does not require more explanation, as it is universally used.
• It attracts the attention of the viewers or readers, as it has many attractive images.

The different steps to make a pictograph are given below:

Step 1: Collect the Data

The first step in making a pictograph is the collection of relevant information, which we want to represent. Once the data is collected, make a table or a list of data.

Step 2: Select the Symbol or Images

To represent the data, pick any images/pictures or symbols. For example, if the data represents the rainfall for different cities, make use of cloud images or some other images which are relevant to the data. 

Step 3: Assign a Key

While representing the data using images, use a key, which denotes the value of the image. Because, if the frequency of the data is too high, then one image is not enough to represent the data. Thus, the numerical value called “key” is used, which should be written along with the pictograph.

Step 4: Draw the Pictograph

While making a pictograph, use two columns that represent the category and data. Finally, draw the pictograph using symbols/images, which represents the frequency. In case, if the frequency is not a whole number, the symbols can be drawn as fractions.

Step 5: Review the Data and Pictograph

Once the pictograph is drawn, make sure that the images exactly represent data as well as the labelling of the pictograph.

Let us consider an example, which will tell us how to interpret data using pictographs. In the given figure, the data of 100 students has been collected, who like different colours. The data given was as follows:

The data above can be represented as a pictograph as follows:

As we can see that the given data becomes more visually appealing and easy to interpret. Suppose, a question was asked, what is the difference between the students who like blue and red colours? By seeing the pictograph, we can directly interpret that there is a difference of 3 STUDENT and 1 STUDENT is equal to 5 students. So, the difference is of 15 students.

Consider another example in which the centimetre height of rainfall in different cities is given.

Let us draw a pictograph for the given data and try to interpret the given information.

Where each CLOUD represents 10 cm rainfall. Now, let us try to interpret some information from the above pictograph.

1. Which city had maximum rainfall as per the given data?

Delhi reported maximum rainfall, as the number of  CLOUD is maximum for Delhi and since each  CLOUD represents 10 cm rainfall, we have in total 12  CLOUD in Delhi, which means 120 cm of rainfall.

2. What is the sum of the total rainfall in all cities?

Frequently Asked Questions on Pictograph

What is meant by pictograph.

A pictograph is a way to represent the data using images or symbols. It represents the frequency of the data using images. Each image represents the frequency of the data.

What is meant by key in pictograph?

In a pictograph, a key represents the value of the image. If the frequency of the data is too large, a key is useful, which should be represented along with the pictograph.

Mention the different steps involved in making a Pictograph?

The steps involved in making pictographs are: Collect the data Select the image or symbol Assign a key Draw the pictograph Review the data

What are the advantages of using pictographs?

It helps to express large information in a simple way. It is easy to understand It easily attracts the viewers as it uses attractive images It does not require a lot of explanation

Metrics details

ONE of the characteristics of scientific management in modern industry is the use which is made of graphical methods. The importance of the pictorial representation of facts and data has also been widely realised by the various movements aiming at the prevention of accidents whether in industry or in the streets. It is, however, only within the last ten years that pictorial representations have been fashioned on definite scientific principles, and the value of the pioneer work of the Mundaneum Institute, Vienna, is now becoming widely recognised. During the last decade, under the leadership of Dr. Otto Neurath, basic principles for visual presentation have been developed. Charts or illustrations constructed on these lines reveal what is most essential at a first glance; the important details stand out on a second glance and more exact details are evident to a third glance. The method has been applied with conspicuous success to technical and to social facts and data, and the work of the Mundaneum has become known through a series of publications such as Gesellschaft und Wirtschaft, Technik und Menschhiet, Die Bunte Welt and Bildstatistik. Branches have now been established in Amsterdam and London (c/o World Association for Adult Education, 16, Russell Square, W.C.I) through which the services offered, including the preparation of charts, the loan of exhibits, issue of publications and provision of material, and advice on principles of visual presentation may be more accessible. The new technique provides an international cultural factor of high importance, but if its full advantages are to be reaped, its introduction into different countries should proceed on uniform lines under the guidance of the Mundaneum itself.

What is Big Data Visualization

There is a huge amount of data in today's information-based environment, and organizations and businesses tend to suffer under that burden. "Big Data" is something that refers to huge amounts of data coming from different sources – social media, transaction records, or sensors. Such data is so massive and complex that even traditional data processing tools fail to deal with it. That's where Big Data Visualization comes in as a way of processing raw data into visible formats for better interpretation and analysis. This article explores what Big Data Visualization is, why it matters, and how it can be harnessed most efficiently.

What is Big Data Visualization?

It is the graphical representation of big data complex and large in volume. While simple data visualization is that which involves amounts of data relatively manageable, Big Data Visualization refers to techniques and tools that have been designed to handle and make sense of very large data sets. It aims at presenting data in such a way that various patterns, trends, and insights may be brought to attention that are not easily discernible from raw data.

Big Data Visualization , therefore, transforms big volumes of data into interactive charts, graphs, maps, and dashboards. This will enable users to gain insights at a glance rather than sifting through raw data themselves. Effective visualization of complex data thus makes it more accessible and understandable, leading to better decision-making and strategic planning.

Importance of Big Data Visualization

1. Better Data Interpretation: Big Data Visualization helps to assimilate big data into picture formats that are easily interpretable. Through visualization, complex patterns and correlations become more vivid, allowing stakeholders to rapidly get an intuitive feel for what data says.

2. Improved Decision Making: Data can be rendered as graphics, which enables a decision-maker to visually identify trends, outliers, and correlations. This means they will have more informed and timely decisions, thereby drastically changing business outcomes.

3. Improved Data Analysis: The visual tools help streamline analyses through key metrics and trends. Users can then interact with the visualizations to drill down into specific data points, run alternative scenarios, and conduct what-if analyses.

4. Effective Communication: Visualization fills the gap between data scientists and non-technical stakeholders. It helps to communicate data-driven insights across teams clearly and effectively, thereby enhancing collaboration and understanding.

5. Real-Time Monitoring: Most of the Big Data Visualization tools are equipped with analytics features for real-time. This tool lets organizations monitor live data streams and make decisions based on the latest information available.

Techniques and Tools for Big Data Visualization

1. Dashboards: An amalgamation of various visualizations into one interface, allows the user to interact with several data views. The most well-known tools are Tableau and Microsoft Power BI , where the majority are described as giving a rich overview of the main points belonging to the key metrics of key business measurements.

2. Heat Maps: Heat maps are matrices that replace data values with colors. This kind of visualization can be applied whenever one is considering intensity across categories or geographic locations. For example, it can be applied to illustrate hot spots of customer activity on a website.

3. Geospatial Visualization: Geospatial visualization takes data points and plots them on geographical locations. This is quite valuable when it comes to location-based analysis, for example, sales performance in different regions and patterns in traffic.

4. Network Graphs: Network graphs show how different entities are connected and is indeed used to analyze social networks, supply chains, and other complex systems.

5. Time-Series Charts: A time-series chart plots data points over time and thus helps to identify trends and seasonal patterns. They can be used to monitor metrics for sales performance, website traffic, and stock prices.

Best Practices on Big Data Visualization

1. Define Goals: Clearly define what you want to say or questions you want to have answered prior to creating any visualizations. This allows you to ensure that your visualizations will be applied to the purposes to which you want to make some meaningful decisions.

2. Choose the Right Type of Visualization: Choose the type of visualization best suited for your data and objectives. Various types of visualizations apply under different circumstances, so choosing the right visualization for your data means you get the best possible picture of your data accordingly.

3. Data Integrity: Ensure that data being graphed is correct and timely. Otherwise, wrong data or old data may very well offer a wrong head or misleading aspects of conclusions leading to bad decisions.

4. Design for Readability: Design to be clear and simple while visualizing information. Set out to avoid cluttering and ensure that information of importance is available and prominent. Use color and design elements to highlight trends or points of interest in the data.

5. Engage with the data: Design interactive features that would allow users to drill down into further analysis of the data. What interactivity-more inclusive of filters and drill-down functionality is what enables the user to move beyond merely knowing something on a surface level into an ability to know something deeper.

Big Data Visualization will, therefore, represent a vital tool in dealing with and interpretation of massive amounts of data that are being produced in the modern digital landscape. Organizations will be able to unveil even more valuable insights that can further support better decision-making, enhance communication with the world at large, and contribute to their competitive advantage as global players or corporates by turning complex data into visual formats. As the volume and complexity of Big Data continue to grow, mastering Big Data Visualization will become indispensable to remaining competitive and making informed decisions in the new world of data.
