Quizplus · Accepted Answer

The Solomon four-group design allows for testing the effects of pretesting and experimental treatments while controlling for potential confounding variables. It includes two experimental groups (one with pretesting, one without) and two control groups (one with pretesting, one without), allowing for a thorough analysis of the effects of pretesting and experimental treatments on the outcome variable.
