### variance1.0

#### variance list

Reports the sample variance of a list of numbers. Ignores other types of items.

(Note that this computes an unbiased estimate of the variance for a sample, rather than for a whole population, using Bessel's correction.)

The sample variance is the sum of the squares of the deviations of the numbers from their mean, divided by one less than the number of numbers in the list.
