- SampleVariance[ <List of Raw Data> ]
- Returns the sample variance of given list of numbers.
- Example:
SampleVariance[ {1, 2, 3, 4, 5} ]
yields a = 2.5.
- SampleVariance[ <List of Numbers>, <List of Frequencies> ]
- Returns the sample variance of given list of numbers considering the frequencies.
- Example:
SampleVariance[ {1, 2, 3, 4, 5}, {3, 2, 4, 4, 1} ]
yields a = 1.29.
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}.
