WebDec 7, 2014 · In this regard, the standard deviation is the size of the distribution, that's why skewness and kurtosis are normalized by size. You could also say that standard deviation belongs to mechanics, and skewness and kurtosis to geometry. Therefore, no, we don't need to have them in units of measure of the variable. Size and shape are separate.
