Meaning and definition of Coefficient of Variation. The coefficient of variation (CV) refers to a statistical measure of the distribution of data points in a data series around the mean. It represents the ratio of the standard deviation to the mean.alculating the coefficient of variation. The main steps involved in computation of coefficient of variation are: 1. Compute the sample mean, using the formula Î¼ = 'x i / n, where n indicates the number of data point x i in the sample, and the total is over all values of i. The term i is read as a subscript of x. 2.
