The pre-post two-group quasi-experimental design described in Figure TB 10-1 is an example of a non-equivalent groups design. This type of design lacks random assignment to groups, which means that the groups are not necessarily equivalent at the beginning of the study, and therefore it is harder to draw causal inferences.
