The control group serves as a baseline comparison for the experimental group. In this experiment, the control group does not receive any stress management techniques but is still measured for the effect of stress reduction. This helps to determine whether the observed changes in the experimental group's stress levels are solely due to the stress management techniques or to other factors such as placebo effects, natural fluctuations, or regression to the mean. Option A is incorrect because the control group should be measured for the effect. Option B is incorrect because the control group should not receive a random stress management technique as this would introduce variability and confound the results. Option D is incorrect because the control group should receive a different treatment than the experimental group to serve as a comparison.
