the algebra 2 test i talked about yesterday was HORRIBLE. Everyone thinks they failed. I'm at the top of my class and i still think i got a 20 on it. The problems were so complicated and weird.

we were somehow supposed to "remember" this formula for prior knowledge. I have never even heard of it.

σ = sqrt[Σ(X - μ)² / N]

"σ = sqrt[Σ(X - μ)² / N]"

σ is standard deviation
Σ is summation (fancy word for adding things up)
μ I'm pretty sure is an arbitrary constant, I don't remember using it in alg II
N I think is a constant that increases with Σ but since he didn't post the limits of Σ I can't really tell
