intraclass correlation

the degree of homogeneity among unordered members (people, items, etc.) of a group. For example, it may reflect the level of agreement among different judges rating a specific attribute. It is indexed by the intraclass correlation coefficient (ICC), which ranges from 0 to 1 in value. A larger ICC indicates more homogeneity and thus that a correspondingly smaller proportion of the total variance in a dependent variable is attributable to individual differences within the group. Compare interclass correlation.
