18.1 - Covariance of X and Y | STAT 414

https://online.stat.psu.edu/stat414/lesson/18/18.1

The covariance of X and Y, denoted Cov ( X, Y) or σ X Y, is defined as: C o v ( X, Y) = σ X Y = E [ ( X − μ X) ( Y − μ Y)] That is, if X and Y are discrete random variables with joint support S, then the covariance of X and Y is: …

How to calculate covariance To calculate covariance, you can use the formula: Cov (X, Y) = Σ (Xi-µ) (Yj-v) / n Where the parts of the equation are: Cov (X, Y) represents the covariance of variables X and Y. Σ represents the sum of other parts of the formula. (Xi) represents all values of the X-variable.

The covariance formula is similar to the formula for correlation and deals with the calculation of data points from the average value in a dataset. For example, the covariance between two random variables X and Y can be calculated using the following formula (for population): For a sample covariance, the formula is slightly adjusted: Where:
