In probability theory and statistics, the index of dispersion, 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.

The dispersion coefficient is defined as the coefficient relating the gradient of the mean concentration to the fluctuating component of the flux.

The coefficient of dispersion (COD) is the average difference a group of numbers has from the median. The value is reported as a percentage of the median.

The coefficient of dispersion is how municipalities can determine differences between the assessed values of properties in an area or neighborhood. It gives a broader look at the state of the market, and a way to evaluate how consistent the appraisal of the properties is. The definition of the coefficient of dispersion that is used exclusively ...

The coefficient of dispersion is how municipalities can determine differences between the assessed values of properties in an area or neighborhood. It gives a broader look at the state of the market, and a way to evaluate how consistent the appraisal of the properties is. The definition of the coefficient of dispersion that is used exclusively in dealing with market values and properties is a measure of how much values of a particular variable vary around the mean or median.

In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and ...

Usually represented as a percentage, sometimes θ is thought of as a measure of relative dispersion. A variable with a population standard deviation of σ and a ...

coefficient of dispersion the variance divided by the mean. Where this value is equal to 1 there is a random or POISSON DISTRIBUTION; greater than 1 aggregation or under-dispersion, and a value smaller than 1, indicates an even distribution or over-dispersion (e.g. territoriality in birds).

coefficient of dispersion: the variance divided by the mean. Where this value is equal to 1 there is a random or POISSON DISTRIBUTION ; greater than 1 aggregation or under-dispersion, and a value smaller than 1, indicates an even distribution or over-dispersion (e.g. territoriality in birds).

In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. Since it is based on quantile information, it is less sensitive to outliers than measures such as the Coefficient of variation. As such, it is one of several Robust measures of scale. The statistic is easily computed using the first (Q1) and third (Q3) quartilesfor each data set. Th…
