Matti <matti.jans...@fysik.su.se> added the comment: If we estimate the mean using a sample we loose one degree of freedom so it will be divided by N-1, while if we have the mean independent of the sample it should be divided by N to be unbiased.
i.e. example 1 sqrt(((1-1.5)²+(2-1.5)²)/(2-1)) = 0.7... example 3 sqrt(((1-1.5)²+(2-1.5)²)/(2)) = 0.5 ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40855> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
