Returns the sample variance of given list of numbers.

CAS Syntax

SampleVariance[ <List of Numbers> ]
Returns the sample variance of given list of numbers. If the list contains undefined variables, it yields a formula for the sample variace.
Example: SampleVariance[{x, y, z}] returns \frac{x² - x y - x z + y² - y z + z²}{3}.
