Dr. Fletcher is interested in whether joining a fraternity/sorority causes people to become more concerned about their attractiveness and appearance. He recruits a group of 55 freshmen (25 males, 30 females) who are planning to go through fraternity/sorority recruitment on his campus. After they join, he gives them a measure of attractiveness concern/appearance concern (the Body Concern Scale).

A)Students in fraternities/sororities
B)College students
C)All individuals with low self-esteem
D)University graduates who were in fraternities/sororities

Question

Quizplus · Accepted Answer

Dr. Fletcher's study specifically recruits freshmen who are planning to go through fraternity/sorority recruitment and measures their change in appearance concern after joining. Therefore, the study can only generalize to students in fraternities/sororities, and not to college students or individuals with low self-esteem who are not part of Greek life. It also cannot generalize to university graduates who were in fraternities/sororities, as their experiences may be different from those of current students.
