Quizplus · Accepted Answer

A pre-post control group design involves two groups (control and experimental) measured at two time points (pre-test and post-test). A two-factor mixed design ANOVA is best suited for analyzing the results of this type of design as it allows for the assessment of the main effects of the treatment and the differences between the groups over time, as well as the interaction between the two factors. This provides a more comprehensive analysis of the effects of the treatment than a t-test, two-factor independent-measures ANOVA, or two-factor repeated-measures ANOVA would.
