Mar 26, 2016 · Note that the coefficient of variation (CV) is always dimensionless and is scale invariant. On the other hand, the index of dispersion (ID) is not scale invariant and is dimensionless only when it applies to a dimensionless variable such as a count, as is the case in practice. Both CV and ID are for non-negative variables, but they are used in different contexts.

24.01.2017 · The index of dispersion is also referred to the coefficient of dispersion. However, Dataplot reserves this term for the ratio of the median absolute deviation to the mean. The index of dispersion should typically only be used for data measured on a ratio scale. That is, the data should be have a meaningful zero.

The coefficient of variation is the ratio of the standard deviation to the mean. The index of dispersion is the ratio of the variance to the ...

In probability theory and statistics, the index of dispersion, [1] dispersion index,coefficient of dispersion,relative variance, or variance-to-mean ratio (VMR), like the coefficient of variation, is a normalized measure of the dispersion of a probability distribution: it is a measure used to quantify whether a set of observed occurrences are clustered or dispersed compared to a standard statistical model.

As with the coefficient of variation, the index of dispersion is a ratio that is used to measure the dispersion of a probability ...
