Quizplus · Accepted Answer

The control group is similar to the experimental group in most ways, but does not receive the treatment (variable thought to cause changes in the dependent variable) being tested. This allows researchers to compare the results of the experimental group to the control group and determine if the treatment had a significant effect on the dependent variable. The other answer choices are not correct because a randomly selected group could contain individuals who are not similar in most ways to the primary group of interest, and the treatment group is the same as the experimental group.
