The Principle and Method of Estimating the Statistical Power and Effect Size When Make Z Test

该文以平均数差异显著性检验为例,对实验数据进行假设检验后,继续对其统计检验力和效果大小进行估计的基本原理和方法作一介绍。

This paper taked an example of the statistical analysis of significant difference between mean values, after hypothesis testing the experimental data,this paper briefly introducted the basic principle and methods of estimating the power of test and effect size.
