Coefficient of Variation (CV) - Normalized Root-Mean-Square Deviation - Percent RMS - Relative Standard Deviation (%RSD)
- is a standardized measure of dispersion of a probability distribution or frequency distribution
- it is defined as the ratio of the standard deviation 𝜎 to the mean 𝜇 (or its absolute value, |𝜇|)
- smaller ratio denotes less variation in data
CV - Definition
- 𝐶𝑉 = 𝜎/𝜇
