Can the coefficient of variation be greater than 1? Yes, the coefficient of CV can be greater than 1. This often occurs when the standard deviation of a dataset is larger than the mean. Is a higher or lower CV better? In most cases, a lower CV is “better” due to lower variability...

The coefficient of variation (CV) is a statistical measure of the relative variability, or dispersion, of a set of data points.
(1)CV=σμ Low values of CV (e.g. CV=0.05) indicate a narrow or “tight” distribution, while values greater than 0.5 indicate a broad distribution. Because the coefficient of variation is non-dimensional, comparisons can be made between different properties of a given material, as well as...
The coefficient of variation (CV) is a measure of the dispersion of data points around the mean in a series.
