The sample mean and sample covariance are statistics computed from a sample of data on one or more random variables. They are used to represent the location and dispersion of the distribution of values in the sample, and to estimate the values for the population. The sample mean is an estimator for the population mean, while the sample covariance is useful in judging the reliability of the sample means as estimators and is also useful as an estimate of the population covariance matrix.
