  "definition": "In the experimental design known as the randomized comparative change design a treatment and control group are randomly selected for study. Both groups are administered a pre-test. The treatment group is given the treatment, while the control group is not. Both groups are tested or measured after the treatment. The test results of the two groups are compared. The pretest allows a check on the randomization process, and allows for control of any differences found.",
