A Comparison of Students’ Grade Point Average by Majors in the Faculty of Mass Communication Technology

Abstract

The purpose of this research was to compare the students’ grade point average by majors in the Faculty of Mass Communication Technology, Rajamangala University of Technology Phra Nakhon. It was a one-semester retrospective study of undergraduate students enrolled in year 1-4 of the Faculty of Mass Communication Technology, Rajamangala University of Technology Phra Nakhon in the second semester of the academic year 2021. The sample was calculated and a simple random sampling was randomly sampled by a computer program getting a total of 550. Data on every semester of the student’s grade point average were collected and calculated the level of grade points per credit at various grade levels that students received in each subject. Statistics used in analyzing data are frequency, mean, standard deviation, minimum value and maximum value, and one-way analysis of variance (one-way ANOVA) using Welch Test statistics and compared post hoc multiple comparisons using the Games-Howell test as variances were found among the populations between different groups. The results showed that students’ grade point average was between 2.94 and 3.31. The minimum value of the students’ grade point average was 1.60 and the maximum value of the students’ grade point average was 3.98. The results of the basic consumption test on the equality of the population variance between groups of the students’ grade point average using Levene’s Test of Homogeneity of Variances showed that p < .01 indicates that the population variance between the five groups were significantly different at .01. They had to be analyzed to prove the mean of each group was different by using Welch Test, it found that the students’ grade point average at least one instructional major affected the students’ grade point average in the Faculty of Mass Communication Technology different from other students’ grade point average majors significantly at .01, it relied on the research hypothesis. Therefore, the researcher conducted multiple comparisons using the Games-Howell test, it showed that the students’ grade point average in the Multimedia Technology major affected the students’ grade point average higher than the students’ grade point average in the Advertising and Public Relations Technology major (AP), higher than the students’ grade point average in the Radio and Television Broadcasting Technology major (RT), higher than the students’ grade point average in the Creative Media Technology major (CT), and higher than the students’ grade point average in the Mass Communication Technology major (MCT) significantly at .01.
