Coefficient of Variation-CV in the probability theory and statistics, it is a measure of dispersion of a probability distribution. It is defined as the ratio of the standard deviation to the mean: The coefficient of variation is a dimensionless number that allows comparison of the variation of populations that have significantly different mean values. It is often reported as on a scale of 0 to 100% by multiplying the above calculation by 100. A coefficient of variation of 1 percent would indicate that an estimate could vary slightly due to sampling error, while a coefficient of variation of 50 percent means that the estimate is very imprecise.
