wikipedia: "In statistics, the medcouple is a robust statistic that measures the
skewness of a univariate distribution[1]. It is defined as a scaled
median difference of the left and right half of a distribution. Its
robustness makes it suitable for identifying outliers in adjusted
boxplots[2][3]."
