Relative Measure of Dispersion
We use relative measures of dispersion to measure the two quantities that have different units to get a better idea about the scattering of the data.
Here are some of the relative measures of dispersion:
Coefficient of Range: It is defined as the ratio of the difference between the highest and lowest value in a data set to the sum of the highest and lowest value.
Coefficient of Variation: It is defined as the ratio of the standard deviation to the mean of the data set. We use percentages to express the coefficient of variation.
Coefficient of Mean Deviation: It is defined as the ratio of the mean deviation to the value of the central point of the data set.
Coefficient of Quartile Deviation: It is defined as the ratio of the difference between the third quartile and the first quartile to the sum of the third and first quartiles.

Measures of Dispersion are used to represent the scattering of data. These are the numbers that show the various aspects of the data spread across various parameters.
