I propose adding a basic calculator statistics module to the standard

library, similar to the sorts of functions you would get on a scientific

calculator:

mean (average)

variance (population and sample)

standard deviation (population and sample)

correlation coefficient

+1 for these.

and similar.

I'm not sure about that.  I immediately thought "how about bivariate
linear regression?", but that's actually misleading in many cases.
Doing anything more general is beyond the scope of "like a typical
scientific/statistical hand calculator".

On the other hand, well-commented code showing how to do the bivariate
case would help people to implement more general cases.  Ditto for
other common tasks like chi-square tests.
