Writing Guide for Research Questions

Step 1: identify the research topic.

Begin by selecting a clear research topic or area of interest. Consider the broader field of study and identify a specific aspect that is meaningful, relevant, and researchable.

Example : Suppose your topic is “effects of social media on mental health.”

Step 2: Narrow the Focus

Refine the topic into a specific issue or question. Think about the aspect of social media’s effects on mental health that interests you most, such as anxiety, depression, or sleep.

Example : Narrow the topic to focus on “how social media affects anxiety levels in college students.”

Step 3: Determine the Type of Research Question

Choose the type of research question that best aligns with your research objectives. If you want to describe the relationship, use a descriptive question; if you are exploring causal relationships, use a causal question.

Example : “How does the amount of time spent on social media affect anxiety levels among college students?”

Step 4: Make It Clear and Researchable

Ensure that the question is clear and specific, so it can be answered within the scope of your study. Avoid overly broad questions, and ensure that the question aligns with available research methods and resources.

Example : Refine the question to be more specific: “Does spending more than two hours a day on social media increase anxiety levels among college students compared to those who spend less time?”

Step 5: Check for Feasibility and Relevance

Evaluate whether the research question is feasible to investigate given the resources, time, and methodology available. Additionally, confirm that the question is relevant to current issues or knowledge gaps in your field.

Tips for Writing Effective Research Questions

• Be Specific : Avoid vague language and ensure the question is focused. A specific question provides clarity and direction for the research process.
• Keep It Manageable : Narrow down broad questions to make them achievable within the constraints of time, resources, and study size.
• Use Clear Language : Use simple, direct language to avoid misunderstandings. Ambiguity in research questions can lead to confusion and inaccurate findings.
• Align with Research Goals : Ensure that the question aligns with the study’s purpose, objectives, and methods, making it suitable for the chosen methodology.
• Avoid Leading or Biased Questions : Write questions that are neutral and unbiased, allowing for objective investigation rather than assuming specific answers.

Common Pitfalls to Avoid

• Overly Broad Questions : Questions that are too general or complex are challenging to answer in a single study. Narrow down the focus to create a researchable question.
• Unanswerable Questions : Avoid questions that cannot be answered with empirical data or that lack objective measurement.
• Assumptive Questions : Avoid questions that assume a certain outcome, as they can introduce bias into the research design and analysis.
• Complex Language : Overly complicated language or jargon can make questions difficult to understand. Use clear, straightforward language instead.

Research questions are foundational to conducting structured, effective studies that contribute valuable insights to the field. By understanding different types of research questions and following a clear writing guide, researchers can create questions that direct their study and produce meaningful answers. Whether for descriptive, comparative, causal, exploratory, or evaluative research, well-crafted questions provide clarity and purpose to research, guiding all aspects of the methodology, data collection, and analysis.

415 Research Question Examples Across 15 Disciplines

A research question is a clearly formulated query that delineates the scope and direction of an investigation. It serves as the guiding light for scholars, helping them to dissect, analyze, and comprehend complex phenomena. Beyond merely seeking answers, a well-crafted research question ensures that the exploration remains focused and goal-oriented.

The significance of framing a clear, concise, and researchable question cannot be overstated. A well-defined question not only clarifies the objective of the research but also determines the methodologies and tools a researcher will employ. A concise question ensures precision, eliminating the potential for ambiguity or misinterpretation. Furthermore, the question must be researchable—posing a question that is too broad, too subjective, or unanswerable can lead to inconclusive results or an endless loop of investigation. In essence, the foundation of any meaningful academic endeavor rests on the articulation of a compelling and achievable research question.

Research questions can be categorized based on their intent and the nature of the information they seek. Recognizing the different types is essential for crafting an effective inquiry and guiding the research process. Let's delve into the various categories:

• Descriptive Research Questions: These types of questions aim to outline and characterize specific phenomena or attributes. They seek to provide a clear picture of a situation or context without necessarily diving into causal relationships. For instance, a question like "What are the main symptoms of the flu?" is descriptive as it seeks to list the symptoms.
• Explanatory (or Causal) Research Questions: Explanatory questions delve deeper, trying to uncover the reasons or causes behind certain phenomena. They are particularly common in experimental research where researchers are attempting to establish cause-and-effect relationships. An example might be, "Does smoking increase the risk of lung cancer?"
• Exploratory Research Questions: As the name suggests, these questions are used when researchers are entering uncharted territories. They are designed to gather preliminary information on topics that haven't been studied extensively. A question like "How do emerging technologies impact remote tribal communities?" can be seen as exploratory if there's limited existing research on the topic.
• Comparative Research Questions: These questions are formulated when the objective is to compare two or more groups, conditions, or variables. Comparative questions might look like "How do test scores differ between students who study regularly and those who cram?"
• Predictive Research Questions: The goal here is to forecast or predict potential outcomes based on certain variables or conditions. Predictive research might pose questions such as "Based on current climate trends, how will average global temperatures change by 2050?"

Here are examples of research questions across various disciplines, shedding light on queries that stimulate intellectual curiosity and advancement.

• Examples of good research questions

However, developing a good research question is often challenging. But, doing appropriate data analysis or drawing meaningful conclusions from your investigation with a well-defined question make it easier.

So, to get you on the right track, let’s start by defining a research question, what types of research questions are common, and the steps to drafting an excellent research question.

Make research less tedious

Dovetail streamlines research to help you uncover and share actionable insights

• What is a research question?

The definition of a research question might seem fairly obvious.

 At its simplest, a research question is a question you research to find the answer.

Researchers typically start with a problem or an issue and seek to understand why it has occurred, how it can be solved, or other aspects of its nature.

As you'll see, researchers typically start with a broad question that becomes narrower and more specific as the research stages are completed.

In some cases, a study may tackle more than one research question.

• Research question types

Research questions are typically divided into three broad categories: qualitative, quantitative, and mixed-method.

These categories reflect the research type necessary to answer the research question.

Qualitative research

When you conduct qualitative research, you're broadly exploring a subject to analyze its inherent qualities.

There are many types of qualitative research questions, which include:

Descriptive: describing and illuminating little-known or overlooked aspects of a subject

Emancipatory: uncovering data that can serve to emancipate a particular group of people, such as disadvantaged or marginalized communities

Evaluative:  assessing how well a particular research approach or method works

Explanatory: answering “how” or “why” a given phenomenon occurs 

Exploratory:  identifying reasons behind certain behaviors and exploring motivations (also known as generative research because it can generate solutions to problems)

Ideological: researching ideologies or beliefs, such as political affiliation

Interpretive: understanding group perceptions, decision-making, and behavior in a natural setting

Predictive: forecasting a likely outcome or scenario by examining past events 

While it's helpful to understand the differences between these qualitative research question types, writing a good question doesn't start with determining the precise type of research question you'll be asking.

It starts with determining what answers you're seeking.

Quantitative research

Unlike broad, flexible qualitative research questions, quantitative research questions are precise. They also directly link the research question and the proposed methodology.

So, in a quantitative research question, you'll usually find

The study method 

An independent variable (or variables)

A dependent variable

The study population 

Quantitative research questions can also fall into multiple categories, including:

Comparative research questions compare two or more groups according to specific criteria and analyze their similarities and differences.

Descriptive questions measure a population's response to one or more variables.

Relationship (or relationship-based) questions examine how two or more variables interact.

Mixed-methods research

As its name suggests, mixed-methods research questions involve qualitative and quantitative components.

These questions are ideal when the answers require an evaluation of a specific aspect of a phenomenon that you can quantify and a broader understanding of aspects that can't.

• How to write a research question

Writing a good research question can be challenging, even if you're passionate about the subject matter.

A good research question aims to solve a problem that still needs to be answered and can be solved empirically. 

The approach might involve quantitative or qualitative methodology, or a mixture of both. To write a well-developed research question, follow the four steps below:

1. Select a general topic

Start with a broad topic. You may already have one in mind or get one assigned to you. If you don't, think about one you're curious about. 

You can also use common brainstorming techniques , draw on discussions you've had with family and friends, take topics from the news, or use other similar sources of inspiration.

Also, consider a subject that has yet to be studied or addressed. If you're looking to tackle a topic that has already been thoroughly studied, you'll want to examine it from a new angle.

Still, the closer your question, approach, and outcomes are to existing literature, the less value your work will offer. It will also be less publishing-worthy (if that’s your goal).

2. Conduct preliminary research

Next, you'll want to conduct some initial research about your topic. You'll read coverage about your topic in academic journals, the news, and other credible sources at this stage.

You'll familiarize yourself with the terminology commonly used to describe your topic and the current take from subject matter experts and the general public. 

This preliminary review helps you in a few ways. First, you'll find many researchers will discuss challenges they found conducting their research in their "Limitations," "Results," and "Discussion" sections of research papers.

Assessing these sections also helps you avoid choosing the wrong methodological approach to answering your question. Initial research also enables you to avoid focusing on a topic that has already been covered. 

You can generate valuable research questions by tracking topics that have yet to be covered.

3. Consider your audience

Next, you'll want to give some thought to your audience. For example, what kinds of research material are they looking for, and what might they find valuable?

Reflect on why you’re conducting the research. 

What is your team looking to learn if your research is for a work assignment?

How does what they’re asking for from you connect to business goals?

Understanding what your audience is seeking can help you shape the direction of your research so that the final draft connects with your audience.

If you're writing for an academic journal, what types of research do they publish? What kinds of research approaches have they published? And what criteria do they expect submitted manuscripts to meet?

4. Generate potential questions

Take the insights you've gained from your preliminary research and your audience assessment to narrow your topic into a research question. 

Your question should be one that you can answer using the appropriate research methods. Unfortunately, some researchers start with questions they need more resources to answer and then produce studies whose outcomes are limited, limiting the study's value to the broader community. 

Make sure your question is one you can realistically answer.

• Examples of poor research questions

"How do electronics distract teen drivers?"

This question could be better from a researcher's perspective because it is overly broad. For instance, what is “electronics” in this context? Some electronics, like eye-monitoring systems in semi-autonomous vehicles, are designed to keep drivers focused on the road.

Also, how does the question define “teens”? Some states allow you to get a learner's permit as young as 14, while others require you to be 18 to drive. Therefore, conducting a study without further defining the participants' ages is not scientifically sound.

Here's another example of an ineffective research question:

"Why is the sky blue?"

This question has been researched thoroughly and answered. 

A simple online search will turn up hundreds, if not thousands, of pages of resources devoted to this very topic. 

Suppose you spend time conducting original research on a long-answered question; your research won’t be interesting, relevant, or valuable to your audience.

Alternatively, here's an example of a good research question:

"How does using a vehicle’s infotainment touch screen by drivers aged 16 to 18 in the U.S. affect driving habits?"

This question is far more specific than the first bad example. It notes the population of the study, as well as the independent and dependent variables.

And if you're still interested in the sky's color, a better example of a research question might be:

"What color is the sky on Proxima Centauri b, based on existing observations?"

A qualitative research study based on this question could extrapolate what visitors on Proxima Centauri b (a planet in the closest solar system to ours) might see as they look at the sky.

You could approach this by contextualizing our understanding of how the light scatters off the molecules of air resulting in a blue sky, and the likely composition of Proxima Centauri b's atmosphere from data NASA and others have gathered.

• Why the right research question is critical

As you can see from the examples, starting with a poorly-framed research question can make your study difficult or impossible to complete. 

Or it can lead you to duplicate research findings.

Ultimately, developing the right research question sets you up for success. It helps you define a realistic scope for your study, informs the best approach to answer the central question, and conveys its value to your audience. 

That's why you must take the time to get your research question right before you embark on any other part of your project.
