Abstract

This study analyzed how average GPA (grade point average) changes as the number of completed semesters increases based on the estimates of intercept, slope, and quadratic term. The students included in this study are those who was admitted in 2011 and took 6 consecutive semesters. More precisely, it was analyzed if intercept, slope and quadratic term of average GPA were different between gender and selection method. The results showed that the intercept was different between selection method, the slope was different between gender, but the quadratic term was different between neither selection method nor gender.

본 연구는 2011학년도 입학하여 여섯 학기 연속 이수한 학생을 대상으로 평균 GPA의 초기값(intercept), 기울기 (slope), 2차항 (quadratic term)을 구하여 이수학기가 늘어나면서 평균 GPA가 어떻게 변화하는지 분석하였다. 구체적으로 이수학기가 늘어나면서 성별과 모집단위에 따라 평균 GPA의 초기값, 기울기, 2차항에 차이가 있는지 분석하였다. 그 결과 초기값에 영향을 주는 변수는 모집단위, 기울기에 영향을 주는 변수는 성별이며 2차항에 영향을 미치는 변수는 하나도 없었다.
