Question

Quizplus · Accepted Answer

Control groups are used to provide a baseline against which to compare the effects of the independent variables. This helps to determine the effectiveness of the treatment or intervention being tested. A control group allows researchers to see whether any observed changes in the experimental group can be attributed to the independent variable being tested, rather than to other factors.
