Apr 24, 2020 · 变异系数（coefficient of variation）也称离散系数、标准差系数或差异系数，是测度数据离散程度的相对指标。它是一组数据的标准差与其相应的平均值之比，用CV表示。主要 …

The coefficient of variation is the percentage value that provides a variation measure: the relative measure of the standard deviation to the mean value of the data set.

The coefficient variation, on the other hand, is the ratio of the standard deviation to the mean, which is a better measure of variability for variables with different means.

So, what is the measure of variation? The four most powerful and commonly used methods for calculating measures of variations are range, interquartile range, variance, and standard …

Coefficient of Variation: For a random variable, the coefficient variation is its standard deviation divided by its mean. If the random variable is stock return, then the coefficient of variation …
