Coefficient of Variation Detailed Explanation. Coefficient of Dispersion. When two different dispersions with different averages are compared, then the coefficient of dispersion can be calculated … WebVR = l - (proportion of cases in the mode) The value of VR reflects the following logic: The larger the proportion of cases in the mode of a nominal variable, the less the variation among the cases of that variable. By subtracting the proportion of cases from 1, VR reports the dispersion among cases. This measure has an absolute lower value of ...

In this study, first, the asymptotic distribution of the ratio of CV of two uncorrelated populations is investigated. Then, the outputs are used to create a confidence interval and to establish a test of … WebMeasures of dispersion describe the spread of scores in a distribution.
