Population and Sample - Definition, Types, Formulas and … Population and Sample Formulas. We will demonstrate here the formulas for mean absolute deviation (MAD), variance and standard deviation based on population and given sample. Suppose n denotes the size of the population and n-1 denotes the sample size, then the formulas for mean absolute deviation, variance and standard deviation are given by; Covariance Formula For Population and Sample With Solved Here, Cov (x,y) is the covariance between x and y while σ x and σ y are the standard deviations of x and y. Using the above formula, the correlation coefficient formula can be derived using the covariance and vice versa.. Example Question Using Covariance Formula.
