高校公共课程“概率论和数理统计”的考试成绩分布规律探索—以扬州大学为例

Study on the Distribution Law of Exam Scores of Public Course “Probability and Mathematical Statistics” in Colleges and Universities—Take Yangzhou University as an Example

摘要: 基于2014~2016年度扬州大学本科生公共课程“概率论与数理统计”的考试成绩，我们针对不同的学生专业，不同的任课教师进行了方差分析，研究发现理工科不同专业的学生成绩不具有显著性差异，管理类不同专业的学生成绩差异却很明显。此外，我们还发现学生专业和任课教师之间存在着交互作用，理工科专业和管理类专业的学生成绩差距明显，不同的教师教授相同的专业或者相同的教师教授同一学科下不同的专业时，学生的成绩差距不是很大。

Abstract: Based on the exam scores of undergraduates’ public course “Probability and Mathematical Statistics” in Yangzhou university during the two-year period of 2014-2016, the method of variance analysis is used to investigate the various students’ majors and different teachers. It is found that the students with different majors form science and engineering disciplines do not have significant differences. Yet students’ performance is marked difference obviously in the diverse majors from management discipline. In addition, we also become aware that there is an interaction between students’ majors and different teachers; the gap between students in science and engineering as well as in management is obvious. However, the student’s performance gap is not great for different teachers who teach the same major or the same teacher who teaches different majors under the same discipline.
