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.

psychonomic

adj. denoting an approach to psychology that emphasizes quantitative measurement, experimental control, and operational definitions, especially in the area of experimental, laboratory psychology. The word was coined to provide a name for the Psychonomic Society, which was created in 1959 by a number of experimental psychologists who were opposed to what they regarded as a swing in the American Psychological Association toward an emphasis on the mental health concerns of psychology. See experimental psychology.
