Within-Variable, Between-Occasion Error Covariances in Models of Educational Achievement.

Wolfle, Lee M.; Ethington, Corinna A.

Educational and Psychological Measurement, v46 n3 p571-83 Aut 1986

Using data from High School and Beyond, this study empirically investigated the extent of within-variable, between-occasion error covariances among variables included in educational achievement models. Little evidence was found to support the statement that reliability estimates for social background variables are inflated because of correlated errors of measurement. (Author/JAZ)
