Default Standard Deviation
I'm looking for a webpage that has a step by step example of calculating standard deviation. Anyone come across something like that online? Everything I've found so far is not easy enough.

ill try to explain it to you :

Find The mean of the set
Subtract the mean from every number in the set
Square each number
Add all of them
Divide by the total number in the set -1 (If there are 5 in the set, divide by 4)
Take the square root.
Walah.
