The Solomon four-group design combines elements of both classical experimental design (two groups: experimental and control with post-test only) and the addition of two more groups with pre-test and post-test measures (creating a total of four groups). This allows for simpler interpretation of the results by allowing for assessment of the influence of pretesting on the outcome measures.
