Sample Mean and Covariance Formula

The sample mean is a set of observations from a given distribution. It is an unbiased estimator of the population mean. Covariance is a measure of how much do the two random variables vary together. It's similar to variance, but where variance tells you how a single variable varies, covariance tells you how two variables vary together. The below given is the Sample mean and covariance formula to estimate the sample mean and the variation among the two variables.
