| 2.2.4 Explanation Section | |
| Explanation | The Solomon four group design is a way of avoiding some of the difficulties associated with the pretest-posttest design.
This design contains two extra control groups, which serve to reduce the influence of confounding variables and allow the researcher to test whether the pretest itself has an effect on the subjects.
Whilst much more complex to set up and analyze, this design type combats many of the internal validity issues that can plague research. It allows the researcher to exert complete control over the variables and allows the researcher to check that the pretest did not influence the results.
The Solomon four group test is a standard pretest-posttest two-group design and the posttest only control design. The various combinations of tested and untested groups with treatment and control groups allows the researcher to ensure that confounding variables and extraneous factors have not influenced the results.
