摘要：本文以华东理工大学本科生高等数学考试成绩为样本,运用皮尔逊χ2准则对成绩是否服从正态分布进行假设检验,将分析结果作为教学管理的参考性依据,并探索性地提出了样本容量规范化的处理方法,认为其有一定的实践意义。
The sample in our study is the examination scores of Advanced Mathematics of East China University of Science and Technology. We use Pearson＇ s criterion chi square to test the hypothesis of the sample data submitting to normal distribution. The result of our study is useful in teaching management. In our research, we have explored a method to standardize the sample size, which is significant in practic.
