Abstract

F. L. Schmidt and J. E. Hunter (1989) critiqued the within-group interrater reliability statistic ( r wg ) described by L. R. James et al (1984). S. W. Kozlowski and K. Hattrup (1992) responded to the Schmidt and Hunter critique and argued that r wg is a suitable index of interrater agreement. This article focuses on the interpretation of r wg as a measure of agreement among judges' ratings of a single target. A new derivation of r wg is given that underscores this interpretation.
