What Is A Good Coefficient Of Variation Percentage? Basically CV<10 is very good, 10-20 is good, 20-30 is acceptable, and CV>30 is not acceptable. Is a high coefficient of variation good? The higher the coefficient of variation, the greater the level of dispersion around the mean. … When we are presented with estimated values, the
What Is CV In Statistics? The coefficient of variation (CV) is the ratio of the standard deviation to the mean. The higher the coefficient of variation, the greater the level of dispersion around the mean. It is generally expressed as a percentage. … The lower the value of the coefficient of variation, the more precise
Which Is Better Standard Deviation Or Variance? The SD is usually more useful to describe the variability of the data while the variance is usually much more useful mathematically. For example, the sum of uncorrelated distributions (random variables) also has a variance that is the sum of the variances of those distributions. Why would you
