This study investigated differences in academic achievement between undergraduate students involved with Greek organizations and undergraduate students independent of Greek organizations. Subjects (N=593) were undergraduate students at Murray State University in Murray, Kentucky in the fall semester of 1990, subdivided by sex, Greek status (independents, pledges, or actives), and college major. Using a Composite ACT score prerequisite, an F-test was performed on the grade point averages (GPA) of the students. The study hypothesized that college students independent of Greek social organization would perform higher academically than members of Greek social organizations, and that "active" members of the organization would perform higher academically than "pledges" of these Greek organizations. Results of the study indicated that independents performed higher academically than pledges. Statistical data did not support the hypothesis that independents achieved higher academically than members of Greek organizations. No conclusions could be drawn dealing with actives. However, females in the study did have a significantly higher GPA average than the males. Includes 22 references. (Author/LPT)
