Question

Dr. Prather randomly assigns 100 student volunteers who experience test anxiety to either a group that will receive training in relaxation exercises or a group that will sit in a waiting area for the same length of time as those learning relaxation. Based on her results, Dr. Prather will have evidence of:

a. How effective the waiting time is.
b. Whether or not relaxation exercises may cause an alleviation of symptoms of test anxiety.
c. How students with test anxiety behave in a classroom setting.
d. How well relaxation exercises works in the treatment of various mood disorders.

Answer 1

b. Whether or not relaxation exercises may cause alleviation of symptoms of test anxiety.

Explanation:

Dr. Prather randomized students who experience anxiety before exams, therefore the idea isn´t to know how effective the waiting time is since otherwise, he would have done an exercise about the waiting time mainly (a).

The problem is not how students behave anxiously before exams, rather if relaxation exercises can help reduce anxiety. (C )

The fragment only mentions students with anxiety, doesn´t refer to other mood disorders (d)

Therefore, according to the results, Dr. Prather will have evidence of whether relaxation exercises may or may not cause alleviation of symptoms of test anxiety, by making a comparison between students who received training in relaxation exercises and those who were in the waiting area and therefore didn´t receive the training.
