Solution
The correct option is C Coefficient of variation
Measure of dispersion is a statistical method to find a specific value from a dispersed series where the extent to which various values of the series tend to disperse from each other or from the average is measured. Coefficient of variation is the coefficient of dispersion based on the standard deviation of the statistical series.
Therefore, Coefficient of variation is a unit less or relative measure of dispersion as variation is the absolute measure of dispersion.
