The coefficient of variation (CV) describes the standard deviation as a percentage of the mean. Because it has no units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you conclude? Standard deviation (CV) = 100% Mean. Click the icon to view the data sets.
