The Solomon four-group design is the only experimental design listed that directly investigates the impact of a pre-test. This design includes four groups: two that receive a pre-test and two that do not. By comparing the post-test scores of the groups with and without pre-tests, researchers can isolate and measure the impact of the pre-test itself. The other designs listed may control for pre-test bias through different means, but they do not directly investigate its impact.
