WebAug 10, 2024 · The p -value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis. WebFeb 27, 2024 · 若呈现出显著性 (p值小于0.05或0.01,严格为0.01,不严格为0.05),说明不符合正态分布,通常现实研究情况下很难满足检验,若其样本峰度绝对值小于10并且偏度绝对值小于3,结合正态分布图可以描述为基本符合正态分布,亦或改用非参数检验. 在通过正态 …
