Abstract:

For the purpose of studying the variability of the university students’ test scores, this study, which divides 299 students from the same major into five equal groups based on their test scores at the end of the first term and graduation, established a test score transfer matrix according to the rank changes of the students in the two 5 equal groupsBased on this matrix, this paper analyzes the transferring situation of each of the five equal groups, calculates the liquidity rate among the five equal groups, and the non-liquidity rate within a group, egthe percentage of which stayed in the same group with no changeAfter comparing the above calculations with a“perfect transferring matrix”, this paper draw the conclusion that the liquidity of the test scores of the students is low

Key words: university students, test score equal group, long-term variability
