This chapter describes the statistical functions in the library. The basic statistical functions include routines to compute the mean, variance and standard deviation. More advanced functions allow you to calculate absolute deviations, skewness, and kurtosis as well as the median and arbitrary percentiles.
The algorithms provided here use recurrence relations to compute average
quantities in a stable way, without large intermediate values that might
overflow. All functions work on any Python sequence (of appropriate
data-type), but see section
