]]>mu = sum( X * P(X) ) for all values of X.

sigma^2 = P(x) * (X – mu)^2 for all values of X.

so, for a 4-sided die, P(X) = .25 for all values of X.

mu = .25 * 1 + .25 * 2 + .25 * 3 + .25 * 4 = .25 (1 + 2 + 3 + 4) = 2.5

sigma^2 = .25 * (1 – 2.5)^2 + .25 * (2 – 2.5)^2 + .25 * (3 – 2.5)^2 + .25 * (4 – 2.5)^2

= .5 * 1.5^2 + .5 * .5^2 = .5 * (2.25 + .25) = .5 * 2.5 = 1.25

So, sigma = sqrt(1.25).

The only problem is that it is all an approximation. There may be more effective ways to do what you’re looking for. I’d try to help, but I can’t read perl.
