图(1)中红点代表了t_0,曲线代表了检验统计量的抽样分布。红点左侧的检验统计量均比 t_0更接近左侧的拒绝区域,因而蓝色区域(面积)代表了p 值,即 p(T\!\le\!t_0) 值;而右侧检验则恰好相反,绿色区域代表了右侧检验的 p 值,即 p(T\!\ge\!t_0)值。 图(1)--图中的红点为检验统计量值t0;如果为...

P-Vaule 简单来说就是"在Ho为真下,比样本统计量还要极端的机率"当P-Vaule < α 时则应拒绝Ho。由於我们在做检定时求弃却域都必须先求出临界值(k)不过若母体为非常态分配则必须不断代入不同的数值来试所以并不好求,因此我们只要将P-Vaule求出来与 α 做比较,就可以轻易的直接判断是否拒绝Ho了...
This is fine as a visualization, but I don’t think there’s much here beyond the means and variances. Seems a lot of space to devote to demonstrating that men, on average, are bigger than women. There’s other stuff in the paper as well, but my favorite is the p-value of 4.76×...
