在假设检验中,如果当原假设为真时,检验统计量产生的p值近似服从(0,1)上的均匀分布;当备择假设为真时,p值的分布是右偏的,则检验统计量的使用是正确的。 左偏倚分布(skewed left)和右偏分布正好相反。 mean < median mean < mode median < mode 左尾比右尾长 整理编译、图via 箱线图(boxplot) Boxplot ...
向左偏斜(Left-skewed 或 Negative Skewness) 向左偏斜的数据分布特点是数据的长尾部分在左侧,即大部分数据集中在右侧,少部分较小的数值分布在左侧较远的位置。这种分布通常有一个较长的左尾,意味着有一些相对较小但远离中位数的观测值。在直方图上表现为左侧拖出一条“尾巴”。对于这类数据集来说,均值小于中位...

左偏态:left skewed distribution,负偏态(negatively skewed distribution),以尾部命名,左偏态或者叫负偏态的尾部,主要在左侧; 右偏态:right skewed distribution,正偏态(positively skewed distribution),同样地,右偏态或者叫正偏态的尾部,则集中在右侧; 正态分布还是偏态分布(左偏态/右偏态)在函数图像上容易分辨,在统计...
