The statistics module in Python

Mean, median, spread and quantiles without reaching for numpy.

import statistics

runs = [88, 91, 97, 104, 99, 108, 92]

print(statistics.fmean(runs), statistics.median(runs))
print(round(statistics.stdev(runs), 2), round(statistics.pstdev(runs), 2))
print(statistics.quantiles(runs, n=4))
print(statistics.mode([1, 2, 2, 3]), statistics.multimode([1, 1, 2, 2]))
print(round(statistics.correlation(runs, sorted(runs)), 3))

How it works

fmean is the fast float mean; mean is exact for Fractions.
quantiles cuts the data into n groups.
stdev is the sample deviation, pstdev the population one.
