- Variance[List of Numbers]
- Calculates the variance of list elements.
Example:
Variance[{1,2,3}]
yields 0.67.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 2*(a²-3a+3)/9.
