- Variance( <List of Raw Data> )
- Calculates the variance of list elements.
- Example:
Variance({1, 2, 3})
yields 0.67.
- Variance( <List of Numbers>, <List of Frequencies> )
- Calculates the variance of list elements, considering the frequencies.
- Example:
Variance({1, 2, 3} , {1, 2, 1})
yields 0.5.
CAS Syntax
- Variance( <List of Numbers> )
- Calculates the variance of list elements. If the list contains undefined variables, it yields a formula for the variance.
- Example:
Variance({1, 2, a})
yields \frac{2}{9} a^{2} - \frac{2}{3} a + \frac{2}{3}.
