《小白爱上SPSS》课程 #统计原理 配对样本的秩和检验 配对样本的秩和检验是指在总体分布未知的情况下,推断两个相关样本所在总体分布是否有差异,常用Wilcoxon检验(符号秩检验),也称为配对设计的符号秩和检验。 配对样本的秩和检验是Wilcoxon提出的,该方法用于推断总体中位数是否等于某个特定值(详见第十一讲:单样本秩...
经上述菜单操作,默认输出(SPSS 23 64位)的统计结果中包括2个统计表: 图5-1-3 Wilcoxon符号秩检验的结果显示,在空气采样结束后,两种不同的保存时间(120h vs 4h)汞含量的测定结果,差异没有统计学意义(T=25,P=0.799T=25,P=0.799)。 注意: Wilcoxon符号秩检验,在进行双侧检验(最为常用)时,取正、负秩和中...
