Steven D'Aprano added the comment:
Off the top of my head, I can think of three APIs:
(1) separate functions, as Nick suggests:
mean vs weighted_mean, stdev vs weighted_stdev
(2) treat mappings as an implied (value, frequency) pairs
(3) take an additional argument to switch between unweighted and weighted modes.
I dislike #3, but will consider the others for 3.5.
