measures of variation
1variation — (statistical) The greater part of empirical research is concerned with the characteristics of groups, or aggregate social entities, rather than individual cases; that is, with men or women in general, rather than any particular man or woman. A… …

3Variation ratio — The variation ratio is a simple measure of statistical dispersion in nominal distributions; it is the simplest measure of qualitative variation.It is defined as the percent of cases which are not the mode::mathbf{v} := 1 frac{f m}{N}.While a… …

5Total variation — As the green ball travels on the graph of the given function, the length of the path travelled by that ball s projection on the y axis, shown as a red ball, is the total variation of the function. In mathematics, the total variation identifies… …
6Convergence of measures — In mathematics, more specifically measure theory, there are various notions of the convergence of measures. Three of the most common notions of convergence are described below. Contents 1 Total variation convergence of measures 2 Strong… …
7WEIGHTS AND MEASURES — From the earliest period of their history the Jews were alive to the necessity of an accurate system of weights and measures, and an honest handling of them. The first legislation in the interest of economic righteousness in general is found in… …
8Qualitative variation — An index of qualitative variation (IQV) is a measure of statistical dispersion in nominal distributions. There are a variety of these, but they have been relatively little studied in the statistics literature. The simplest is the variation ratio …
9Explained variation — In statistics, explained variation or explained randomness measures the proportion to which a mathematical model accounts for the variation (= apparent randomness) of a given data set. Often, variation is quantified as variance; then, the more… …
10Human genetic variation — is the natural variation in gene frequencies observed between the genomes of individuals or groups of humans. Variation can be measured at both the individual level (differences between individual people) and at the population level, i.e.… …
