The Solomon four-group design is specifically used to control for the effects of pre-testing on the participants' responses in experimental research, thereby minimizing the threat of testing to validity. This design involves four groups where two groups receive a pre-test and two do not, allowing researchers to assess the impact of the pre-test on the experimental results.
