- SampleVariance[ <List of Numbers> ]
- 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 variance.
- Example:
SampleVariance[{x, y, z}]yields \frac{x² - x y - x z + y² - y z + z²}{3}.
