    Controlled experiments provide a methodology to reliably evaluate ideas. Unlike other methodologies, such as post-hoc analysis or interrupted time series (quasi experimentation) (5), this experimental design methodology tests for causal relationships (6 pp. 5-6). Most organizations have many ideas, but the return-on-

    should adopt before using online controlled experiments at scale. Experimentation is not a panacea for everyone, and the assumptions should be understood. 2. We discuss cultural and organizational issues, including two topics not commonly discussed: the cost/benefits of running controlled experiments, and running negative experiments. 3.

    The controlled experimentis a two-group experiment, consisting typically of an experimental group and a control group. In this experimental design, which allows the determination of causality, the independent variable is the factor that the experimenter is manipulating. For example, in a drug effective-ness experiment, the independent variable ...

In the fertilizer example, the investigator must be sure that the peanuts don't grow just as well with no fertilizer at all. The control would be a treatment in which no fertilizer is applied ...

  7. PDF Section 1.3 What does it mean to have a "controlled" experiment?

    They focus more on all the aspects of what it means to be a "controlled" experiment. Our text spends most of the attention on the very essential part of it - the random assignment of the values of the explanatory variable to the subjects. A more traditional text would emphasize these three aspects of "control" in a controlled experiment.
