A team of doctors is testing the effects of a new drug on sickle-cell anemia patients. The team organizes the patients into two groups. The experimental group is given the drug. The control group is given a placebo, or a substance that has no medicinal value. Neither group knows whether they received the drug or the placebo. Why is having a control group an important part of this experiment?
Scientists can determine the effects of the drug by comparing those patients that have been treated with the drug to those that have not.
By having two groups, it allows the scientists to have a larger sample size on which to test the drug.
It provides the patients with a choice of whether they want to take the experimental drug.
Scientists are able to study the effects of a second drug on the group that received the placebo.
