Thomas R. Knapp

Journal of Educational and Behavioral Statistics, 1977, vol. 2, issue 3, 171-186

Abstract: This paper summarizes the interrelationships among within-aggregate, between-aggregate, and total-group correlation coefficients, with artificial and “real-data†examples. It also discusses the relevance of correlation analyses at various levels of aggregation and some of the difficulties encountered in cross-level inference.
