Quizplus · Accepted Answer

The Solomon four group design is specifically structured to assess the potential interactions between pre-testing and the experimental treatment, making it the least concerning in terms of interaction effects. This design includes groups that receive both pre-tests and post-tests, groups that receive only pre-tests, groups that receive only post-tests, and groups that receive neither, allowing for a comprehensive analysis of how pre-testing might interact with the treatment effect.
