Comment(by craigcitro):
Two quick comments:
* With the mean function, dividing by `len(a_list)` is '''really'''
dangerous -- for instance, if you give the function a collection of Python
`int`s, then it will do Python `int` division -- so `3/2 = 1`, etc. Bad
news.
* Do we want to use the name `std` for standard deviation? Since the
other systems (e.g. R) use that, we should have it available, but I would
also like to have the full `standard_deviation` available (especially
since we have `variance` as opposed to just `var`, for obvious reasons).
