Coefficient Of Variation Example . Coefficient of variation, cv is defined and given by the following function: For the pizza delivery example, the coefficient of variation is 0.25.

For the iq example, the variance = 14.4 2 = 207.36. While it is most commonly used to compare. In the field of statistics, we typically use different formulas when working with population data and sample data.
If we wish to compare the variability of two or more series, we can use the coefficient of variation.
Erin, the coefficient of variation of any value could be dictated by different sources of variation , for example, sampling methods , processing methods, procedural methods etc ,. The coefficient of variation (cov) is a measure of relative event dispersion that's equal to the ratio between the standard deviation and the mean. It is calculated as follows: For the iq example, cv = 14.4/98.3 = 0.1465, or 14.65 percent.
