In this blog I discuss a bug that I found in Python 3.6.4 statistics module version 3.4 concerning the computation of the median, median_high and median_low function when missing values (NaN, nan) are present in the data.
I reported this bug to the Python team and had investigated it with different data, with all results pointing to a bug in the current version.
