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). In addition to measuring the group of participants who joined a fraternity/sorority, Dr. Fletcher decides to give the same measure to another group of 55 participants who decided to not join a fraternity/sorority. This type of design is known as a(n):

Answer 1

Answer: nonequivalent control group design

Explanation: In a nonequivalent control group design, the subjects or parcipants in an experiment are not randomly assigned to experimental groups. Only subjecys who fits into a particular group are assigned, just like in the context above, whereby sorority or fraternity groups only contains subjects who are interested in joining and the control group contains subjects who have no interest. This non similarity which exists between the experimental groups due to the exclusion of randomness in the group assignment reaukts in non equivalence.

Answer 2

Nonequivalent control group design

Step-by-step explanation:

This type of design in a project is characterized by the adoption of participants that do not fit the experimental groups that the project established, that is, these participants do not receive the factor that is being tested in the experiment, forming a group of individuals that will serve as a comparison between participants who received the tested factor and participants who did not receive the tested factor.

In the case of the research project above, some participants do not intend to join a fraternity, so they will be the control group and will serve to compare the differences between the influence of appearance between people who want to join fellowships or not.
