The Comparative Reliability of Simple and Residualized Difference Scores: A Corrigendum and a Note on the Reliability of Simple and Residualized Differences.

Zumbo, Bruno D.; And Others

Journal of Experimental Education, v61 n1 p81-85 Fall 1992

An error in an essential equation within the article by Williams and Zimmerman is corrected, and the algebraic inequalities are translated into questions a researcher can ask about simple or residualized difference scores. Williams and Zimmerman acknowledge the error and note that main conclusions are not affected. (SLD)
