Assessing Differences Between Grouped and Individual-Level Regression Coefficients.
Two questions are investigated here: What should the unit of analysis be in investigations of educational effects and on what basis should the units be chosen Under what conditions can relationships among measurements on individuals be estimated from the relationships among measurements on aggregates of individuals? Models using standard analysis of variance, standard analysis of covariance, and standard regression analysis are compared as they would be applied to two different data aggregation levels. Implications for multilevel analysis are discussed. (Author/BW)
