Question

Quizplus · Accepted Answer

A control group is necessary to minimize the effects of maturation because it allows for a comparison of groups that have similar experiences except for the treatment. The control group receives no treatment, which helps to isolate the effects of the treatment group from other variables that could affect the outcome. Placebo, experimental, and investigational groups may not necessarily provide a comparison group that is free of variables that can influence the outcome.
