Quizplus · Accepted Answer

The control group in this study is the group that does a daily yoga workout because they serve as the comparison group for the experimental group that does a daily cardio workout. The control group allows the researcher to compare the effects of the different types of exercise while holding other variables constant. The groups with higher or lower IQs are not relevant to determining the control group in this study.
