Alsawalmeh, Yousef M.; Feldt, Leonard S.
Educational and Psychological Measurement, v59 n3 p373-83 Jun 1999
Develops a statistical test for the hypothesis that alpha'(1) =alpha'(2) when alpha'(1) is the Spearman-Brown extrapolated value of Cronbach's alpha reliability for test 1 and alpha'(2) is the unadjusted coefficient for test 2. The test is shown to exercise tight control of Type I error. (Author/SLD)
