# coefficient of dispersion

## 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).Want to thank TFD for its existence?
