Question

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). If Dr. Fletcher is interested in a causal relationship between joining a fraternity/sorority and attractiveness/appearance concern, why doesn't he conduct a true experiment? O Because it is not possible to measure body concern.
