statistics.pvariance() - statistics

Return the population variance of data, a non-empty iterable of real-valued
numbers.  Variance, or second moment about the mean, is a measure of the
variability (spread or dispersion) of data.  A large variance indicates that
the data is spread out; a small variance indicates it is clustered closely
around the mean.
