大学生考试成绩“扎堆”现象的统计分析

Statistical Analysis on the Phenomenon of Undergraduate Test Scores ‘Flock Together'

用数理统计的方法,分析了以寝室为单位的两个大学生班级的考试成绩分布情况,结果表明,考试成绩存在"扎堆"现象,即某些寝室的多数学生的成绩都在良好(80分)以上,而另一些寝室多数学生的成绩为不及格。这一现象说明影响学生学习成绩的因素除学生的基础、学习方法,以及校风和班风外,还有寝室内的学风(简称为"室风"),甚至这一因素的影响更显著。这一结论对学生管理工作者的工作具有指导意义。

By adopting the method of mathematical statistics, the paper analyzes test scores distribution of two undergraduate classes which takes a dormitory as a unit. The result indicates that the phenomenon of undergraduate test scores 'flock together' is existing, that means most students' test scores in some dormitories are good( above 80scores), but in some other dormitories, most students fail. This phenomenon explains that the style of study in dormitory(referred as the ‘style of dormitory') is a factor, even an important factor that could influence the undergraduate test scores besides the students' basis, study methods, school spirits and style of class. This conclusion has guidance significance in the works of students' administrators.
