假设检验中的保护原则

Protecting Principle in Hypothesis Test

在假设检验中,会发现这样一种现象:对于给定的样本,在相同的显著性水平下,无论在原假设中假设样本的均值大于还是小于母体的均值,检验结果均为接受原假设.针对这一矛盾,利用Matlab语言,对假设检验问题进行计算分析,深入剖析了假设检验保护原假设的思想,并结合实例给出了具体说明.

There exists certain kind of phenomenon: under the same remarkable level, for the given sample, no matter the average sampling value in the original hypothesis is supposed to be higher or lower than the total average value, the conclusion will turn out accepting the original hypothesis. In this paper, this contradiction is analyzed through practical calculating example by using Matlab language, and the thought of 'protecting original hypothesis' of hypothesis test is thoroughly analyzed.
