Are you sure you're not confusing Delta and Sigma σ?

Trying to think why you'd be using delta in statistics... Sigma's the prominent one.

In my book it says µ=E(X)

I assume you know what that means

[Fez of Mahrez]

Stats the way, uh huh, uh huh, I like it, uh huh, uh huh.

In my book it says µ=E(X)

I assume you know what that means

Or Biology.

Err what?

You know that E(x) means expected and Var (x) means variance, tusk tusk indeed.
