    • 2 Group, Post-test Comparison: The main advantage of this design is randomization. The post-test comparison with randomized subjects controls for the main effects of history, maturation, and pre-testing; because no pre-test is used there can be no interaction effect of pre-test and X. Another advantage of this design is that it can be extended to include more than two groups if necessary.
