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;
