The standard deviation (?, pronounced sigma) of a set of values is a measure of how much the set of values deviates from the average of the values. To calculate ? of a complete set of values (as opposed to a sampling),...

1. Calculate the average of the set (the sum of the values divided by the quantity of the values).
2. Calculate the difference between each value and the average calculated in step 1, then square the difference.
3. Calculate the average of all the squares calculated in step 2.
4. The standard deviation is the square root of the average calculated in step 3.
