Question

Quizplus · Accepted Answer

Nonequivalent control group design is used when researchers cannot randomly assign subjects to treatment and control groups (e.g. ethical or practical reasons). Therefore, the answer is D, because all other options (less cost, less time involved, easier training) are not necessarily advantages of using nonequivalent control group designs, and are not the main reasons why this design is used.
