FUNCTION The function calculates Skewness

The Skewness of a data set is a measurement of the asymmetry of the distribution about the mean.

A Skewness of zero indicates perfect symmetry:

A positive Skewness indicates that more values lie below the mean and the distribution has a 'tail' which extends towards the higher values;

A negative Skewness indicates that more values lie above the mean and the distribution has a 'tail' which extends towards the lower values.
