I wrote not ok formula for median_grouped. But i can't get idea from source. THIS SHOWS that source code is NOT ok doc, even student can't get it
e.g. pvariance.
Calculates population variance of iterable. It's given by formula:
pvariance([x1, x2, ..., xN]) = ((x1 - M)**2 + ... + (xN - M)**2) / N,
where M is mean of all values:
M = (x1 + ... + xN) / N |
