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

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).

What Is A Coefficient of Dispersion (COD)?

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 ...

Note: Note that there are various other definitions for the coefficient of dispersion. It is sometimes defined as COD = VARIANCE/MEAN To compute this statistic in Dataplot, use the command

Dec 28, 2021 · 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.

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 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 Karl Pearson Coefficient of dispersion is simply the ratio of the standard deviation to the mean. Green's COD (Cx) is suitable when dealing ...

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…

The coefficient of dispersion is how municipalities can determine differences between the assessed values of properties in an area or neighborhood.

100 times the coefficient of dispersion based on standard deviation is the coefficient of variation (C.V.). C.V. = 100 × (S.D. / Mean) = (σ/ȳ ) × 100. Solved ...

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 ...

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 in dealing with market values and properties is a measure of how much values of a particular variable vary around the mean or median.
