Abstract:
The purposes of this research were to investigate the types of distributions of cumulative and yearly grade point averages of students at the Faculty of Education, and to make the comparisons of these distributions among themselves and with relevant normal distributions. The samples used in this study were cumulative and yearly grade point averages of 1372 students, four-year bechelors degree program, Chulalongkorn University, during the academic years of 1972 to 1978. The findings are as follows: 1. About 84.67% of 1372 students received the degree, 12.22% and 3.12% received the degree with second and first class honors, respectively. The median scores of the data are ranged from 2.76 to 2.82 and the quartile deviations from 0.23 to 0.26. 2. The yearly grade point averages of these 16 groups consist of the median scores ranging from 2.48 to 3.30 in which the minimum score belongs to the class of 1972 first year student group and the maximum one to the 1975 fourth year student group. The quartile deviation scores show the range between 0.25 to 0.32 in which the minimum score belongs to the class of 1972 second year student group and the maximum one to 3 different groups 1975 first year, 1973 second year and 1975 third year groups. 3. The comparisons of yearly grade point averages among freshmen; sophomore; junior and senior students of all four classes, 1972 to 1975 are made. The grade point averages of freshmen are distributed differently, so did to those of the seniors (p<.05) 4.The comparisons are made with the relevant normal distribution. The cumulative grade point averages of those belong to the class of 1974 are distributed differently from the normal distribution (p<.05) and the yearly grade point averages of those belonged to the classes of 1974 and 1975, the first year-student groups; of 1972 to 1975, the third year-student groups; and of 1973 and 1975, the fourth year-student groups; all 8 groups together are distributed differently from the normal distribution (p<.05).
