standard deviation 是标准差 表示一组数值之间的离散程度 计算公式：简 单来说就是一组数据的每一个数与该组数据的平均值比较，通过得出来的数值看这组数据的离散程度。比如，全班男同学身高都差不多是1.75m，那么我们可以 说这个班的男生身高标准差很小，因为大家都接近平均值就是说数据很集中。
“标准差”(standard deviation)也称“标准偏差”，它可以通过计算方差的算术平方根来求得。标准差表征了各数据偏离平均值的距离，它反映出一个数据集的离散程度。计算标准差的步骤通常有四步：（1）计算平均值 （2）计算方差 （3）计算平均方差 （4）计算标准差 例如，对于一个有六个数的数集2,3,4...
