1). Arithmetic
2). Variance
The variance is calculated as the average squared difference between each number and the mean.
variance =
=
=
=
The standard deviation is the square root of the variance.

If a normal distribution, 1 standard deviation from the mean is � which means 68% of values should fall between and

range: to = (inclusive)
