The coefficient of variation (CV) is a relative measure of variability that indicates the size of a standard deviation in relation to its mean. It is a standardized , unitless measure that allows you to compare variability between disparate groups and characteristics.
Coefficient of Variation. The coefficient of variation, CVar, is a “normalized” measure of data spread. It will not be useful for any inferential statistics that we will be doing. It is a pure descriptive statistic.
In probability theory and statistics, the coefficient of variation (CV), also known as normalized root-mean-square deviation (NRMSD), percent RMS, and relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution.

Define and calculate measures of variability. Measures of central tendency (a value around which other scores in the set cluster) and a measure of variability (an indicator of how spread out scores are in a dataset) are often used together to give a description of the data.
16 sty 2021 · Coefficient of variation is the standard deviation divided by the mean; it summarizes the amount of variation as a percentage or proportion of the total. It is useful when comparing the amount of variation for one variable among groups with different means, or among different measurement variables.
The coefficient of variation (CV) is a standardized, dimensionless measure of dispersion relative to a data set's average [1]. It enables the comparison of several datasets [2] with different units of measurement [3, p. 84].
