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.
