A personal trainer believes that his new workout plan of lifting weights combined with cardio may help his clients lose more body fat than a workout plan of just cardio. To test his theory, he asks locals to sign up to participate in his study. 36 men and 24 women sign up for the study. The trainer also thinks the treatment will work differently on men and women. Therefore, he divides the group into men and women and then randomizes the two treatments within each group. The trainer measures the body fat of each participant and then measures it again after three months when the workout plan has been completed.
