### E1.6. Some Useful Properties of Covariance (Econometrics Math)

In this video, I use the formula for covariance to demonstrate logically some of the more useful properties of covariance. In particular, I demonstrate that the covariance of a random variable with itself is the variance. I also show why covariance is symmetric and linear. Finally, I conclude by showing why the computational form for covariance is equivalent to its definition.
