Pearson's moment coefficient of skewness
Description
In probability theory and statistics, skewness is a measure of the asymmetry of the probability distribution of a real-valued random variable about its mean. The skewness value can be positive or negative, or even undefined. The skewness of a random variable X is the third standardized moment.
