Web18 de mai. de 2024 · CV = σ / μ. Simply put, the coefficient of variation is the ratio between the standard deviation and the mean. A CV of 0.5 means the standard deviation is half as large as the mean. A CV of 1 means the standard deviation is equal to the mean. A CV of 1.5 means the standard deviation is 1.5 times larger than the mean. WebAnswer (1 of 2): The “officially correct” answer is that the second central moment (a.k.a., the variance) is larger. Variance is a formula defined for any probability distribution (although it can be infinite), and is simply the sum-of-squared-deviations about the mean. But the general idea is t...
