Explanation:
Detailed explanation-1: -Coefficient of variation is one of the commonest ways of calculating the relative dispersion. It is the ratio of the standard deviation to the mean multiplied by 100 to make a percentage. The value can be used to compare various data sets and their variance.
Detailed explanation-2: -What is the Coefficient of Variation? The coefficient of variation (relative standard deviation) is a statistical measure of the dispersion of data points around the mean. The metric is commonly used to compare the data dispersion between distinct series of data.
Detailed explanation-3: -Variance is an absolute measure of dispersion.
