In [[statistics]], the '''interclass correlation''' (or ''interclass correlation coefficient'') measuresis a measure of a relation between two variables of different classes (types), such as the weights of 10-year-old sons and the weights of their 40-year-old fathers. Deviations of a variable are measured from the [[mean]] of the data for that class – a son’sson's weight minus the mean of all the sons’sons' weights, or a father’sfather's weight minus the mean of all the fathers’fathers' weights.

The [[Pearson correlation coefficient]] is the most commonly used measure of interclass correlation.

The interclass correlation contrasts with the [[intraclass correlation|''intra''class correlation]] between variables of the same class, such as the weights of women and of their identical twins; here deviations are measured from the mean of all members of the single class:, in this example of all women in the set of identical twins.
