Python has a built-in module that you can use to calculate mathematical statistics of numeric data.
The statistics module was new in Python 3.4.

|---|---|
| statistics.harmonic_mean() | Calculates the harmonic mean (central location) of the given data |
| statistics.mean() | Calculates the mean (average) of the given data |
| statistics.median() | Calculates the median (middle value) of the given data |
| statistics.median_grouped() | Calculates the median of grouped continuous data |
| statistics.median_high() | Calculates the high median of the given data |
| statistics.median_low() | Calculates the low median of the given data |
| statistics.mode() | Calculates the mode (central tendency) of the given numeric or nominal data |
| statistics.pstdev() | Calculates the standard deviation from an entire population |
| statistics.stdev() | Calculates the standard deviation from a sample of data |
| statistics.pvariance() | Calculates the variance of an entire population |
| statistics.variance() | Calculates the variance from a sample of data |
