摘要
文章以南京邮电大学通信与信息工程学院、电子科学与工程学院2009级108个宿舍347名学生和2010级106个宿舍330名学生的宿舍与高等数学成绩为依据,运用方差、成绩最大差、宿舍最高分和最低分进行分析,结果显示:同一宿舍学生成绩有一定的集聚性。
The informants are 347 students from 108 dormitories （Grade 2009, School of In- formation and En sity of Posts and gineering and School of Electronic Science and Engineering in Nanjing Univer- Telecommunications） and 330 students from 106 dormitories（ Grade 2010）.
