Term: Intraclass Correlation Coefficient (ICC)
Last Updated: 2009-02-02
The intraclass (sometimes called intracluster) correlation coefficient (ICC) tells us how similar elements in the same cluster (group) are. It provides a measure of homogeneity within the clusters (Lohr, Sharon L. (1999)). It ranges from 0 to 1 with values closer to 1 indicating greater homogeneity.
