Coefficient of Variation or C.V.
To compare the variability between or more series, coeffiecnt of variation is used, it is relative measure of dispersion, it innovated and used by Karl person in1895 for the first time .as such it is known as karl person coefficient of variation, in the words of karl Pearson coefficient of variation is the percentage variation in the mean the standard deviation being treated as the total variation in the mean in other words coefficient of variation is 100 times of coefficient of standard deviation, this measure of dispersion is used to compare the variability homogeneity , stability and consistency between two or more distribution ,the following formula is used. Coefficient of variation = standard deviation /Mean x100.
