Instructions. There are cases where random assignment to conditions is not possible due to ethical constraints or other considerations, which requires researchers to rely on quasi-experiments (Salkind, 2017).
In this exercise, you will analyze four experimental designs reviewed in Chapter 12.
You will also write a summary that briefly reviews the pros and cons of each design.
1. Single-subject designs
2. The nonequivalent control group design
3. Multiple baseline designs
4. Evaluating single-subject designs
