Question

Quizplus · Accepted Answer

A control group is often used in experiments to serve as a comparison group that does not receive the experimental treatment. This helps to establish whether any observed effects are actually due to the treatment or just random variation. Sample, competency, and polling groups may be used in other types of research, but are not as commonly associated with experiments.
