37 These functions calculate an average or typical value from a population
53 These functions calculate a measure of how much the population or sample
107       The sample mean gives an unbiased estimate of the true population mean,
109       ``mean(sample)`` converges on the true mean of the entire population.  If
110       *data* represents the entire population rather than a sample, then
111       ``mean(data)`` is equivalent to calculating the true population mean μ.
298    Return the population standard deviation (the square root of the population
309    Return the population variance of *data*, a non-empty iterable of real-valued
319    Use this function to calculate the variance from the entire population.  To
360       When called with the entire population, this gives the population variance
364       If you somehow know the true population mean μ, you may use this function
365       to calculate the variance of a sample, giving the known population mean as
368       unbiased estimate of the population variance.
394    Use this function when your data is a sample from a population. To calculate
395    the variance from the entire population, see :func:`pvariance`.
437       should be an unbiased estimate of the true population variance.
439       If you somehow know the actual population mean μ you should pass it to the
