Question

Quizplus · Accepted Answer

Increasing the number of subjects in each condition increases the power of the study, making it more likely to detect an effect. Decreasing the number of levels of the independent variable may make the study simpler, but it does not necessarily increase the chances of detecting an effect. Using a two independent groups design or an experimental group-control group design is a matter of research design and does not necessarily increase the power of the study.
