Basic statistics library?

I see math-statistics and statistics2 on the RAA, though I've never
tried either. I think the former has what you're looking for.

Subject: basic statistics library?

Hi Everybody,

I am looking to do some basic statistics in ruby. Mean, Variance,
Standard deviation, etc. Does anyone know if there is a gem or a
library available for this?

More exactly, I want to take test scores for students and
conver them to
A, B, C, D, F. In order to calculate Grade Point Averages.
