CAS Syntax

Covariance[ <List 1 of Numbers>, <List 2 of Numbers> ]
Calculates the covariance using the elements of both lists.
範例:
Covariance[{1, 2, 3}, {1, 3, 7}] yields 2, the covariance of {1, 2, 3} and {1, 3, 7}.
Covariance[ <List of Points> ]
Calculates the covariance using the x- and y-coordinates of the points.
範例:
Covariance[{(1, 1), (2, 3), (3, 7)}] yields 2, the covariance of {1, 2, 3} and {1, 3, 7}.
