Question

Quizplus · Accepted Answer

The Solomon four-group design is the best experimental design to use to determine the effect of a pretest on the dependent variable because it includes two control groups, one of which receives the pretest and one that does not. This allows for the comparison of the groups that did and did not receive the pretest, as well as the comparison of the groups that did and did not receive the intervention. This design also controls for any potential order effects that may occur when participants receive the pretest before the intervention.
