摘要
考试成绩中,60分是一个关键分,本文针对阅卷时可能存在"人情分"的现象,利用假设检验的方法对成绩中的"人情分"进行分析,并用MATLAB实施检验,同时用贝塔分布和伽玛分布进行对比实验,说明检验方法不依赖于成绩分布。
60 points is one of the key points in examination,according to themarking may have ＂ people＂ phenomenon,the result of ＂people＂ was analyzed by using the methods of hypothesis test,and use MATLAB to carry out the inspection,at the same time with the Berta distribution and gamma distribution by experiments,the test method does not rely on in the achievement distribution.
