The links I was interested in while implementing the standard deviation.
Standard deviation in numpy [duplicate] @ Stackoverflow
user1700890 Dec 2 '15 at 19:07 I think default of numpy is population standard deviation, which is N and sample standard deviation is N-1.
It seems that there is a difference between unbiased variance and "other (unknown) variance".

~~ Someone's article mentioned unbiased distribution in the comment section, but I can't find which article it was. ~~ found. Relationship between mathematical formulas and programming

There seems to be the following terms.
--Mother dispersion --Sample variance --Unbiased dispersion
population variance / sample variance / unbiased variance There seems to be.
Also keep in mind the "name confusion" on wikipedia.
