In a RPD (Repeated measures with a pretest and posttest control group) design, only one pretest-posttest score pair reflects the treated group. This is because the design involves one group receiving the treatment and a control group receiving no treatment, with both groups being assessed before and after the intervention. Therefore, the pretest and posttest scores for the control group are used as a baseline measure against which the changes seen in the treated group are compared. The RD (Randomized Design), NEGD (Non-equivalent control group design), and ANCOVA designs do not necessarily involve pretest-posttest score pairs reflecting the treated group.
