Question

James read a magazine ad about a drug that doctors say may help college students perform better on multiple-choice type tests. Being the inquisitive person that he is, James decided to do an experiment to see if the magazine's claims were true. He administered the drug to one of his classes and gave the other class a placebo. James then tested the students in both groups on material they had recently discussed in class. In this example, what is the experimental group?

a) The group that received the drug
b) The group that received the placebo
c) The group that was not tested
d) Both groups are control groups

Answer 1

The experimental group is the group that received the drug, while the control group is the group that received the placebo.

Step-by-step explanation:

The experimental group is the group that received the drug. In this case, James administered the drug to one of his classes, so that class is the experimental group. The control group is the group that received the placebo. James gave the other class a placebo, so that class is the control group.
