Tests for Equality of Several Alpha Coefficients When Their Sample Estimates Are Dependent.

Woodruff, David J.; Feldt, Leonard S.

Psychometrika, v51 n3 p393-413 Sep 1986

This paper presents 11 statistical procedures which test the equality of m coefficient alphas when the sample alpha coefficients are dependent. Several of the procedures are derived in detail, and numerical examples are given for two. (Author/LMO)
