Control groups are an essential part of the scientific method. They allow the scientist to compare two or more groups that are the same expect for one variable. Example, if a group of healthy adults takes a new weight loss drug, exercises 3 days a week, and loses 10 pounds, the scientists couldn't be certain that the drug was the cause of the weight loss unless they had another group (control group) of similar healthy adults that exercised 3 days a week and did NOT take the drug. If the control group also lost 10 pounds without the drug, then they know the drug was NOT the cause of the weight loss.
