Question

Quizplus · Accepted Answer

Dr. Prather's study design involves randomly assigning participants to either the relaxation exercise group or the waiting area group. By measuring their symptoms of test anxiety before and after the intervention, she can determine if there is a significant difference between the two groups. This will provide evidence for whether or not relaxation exercises may cause an alleviation of symptoms of test anxiety. The study design does not allow for conclusions to be drawn about the treatment of mood disorders, behavior of students in a classroom setting, or the effectiveness of waiting time.
