Question

Quizplus · Accepted Answer

The nonequivalent control group should consist of individuals who are comparable to the experimental group but did not experience the independent variable (earthquake). Option A fits this criteria as the students heard of the earthquake but did not experience it and are comparable to the experimental group who did experience it. Option B does not work as the control group needs to be a group that did not experience the earthquake, and option C does not work as it is not a comparable group to the experimental group. Option D may be comparable but does not fit the criteria of not hearing about the earthquake.
