Reliability Estimation for a Test with Parts of Unknown Lengths.

Peer reviewed

Gilmer, Jerry S.; Feldt, Leonard S. – Psychometrika, 1983

Estimating the reliability of measures derived from separate questions on essay tests or individual judges on a rater panel is considered. Cronbach's alpha is shown to underestimate reliability in these cases. Some alternative coefficients are presented. (JKS)

A Modification of Feldt's Test of the Equality of Two Dependent Alpha Coefficients.

Peer reviewed

Alsawalmeh, Yousef M.; Feldt, Leonard S. – Psychometrika, 1994

A modification of a test of the equality of nonindependent alpha reliability coefficients is proposed. It avoids the limitation that the product of the number of test parts times the number of subjects be quite large. Monte Carlo studies indicate that this test can be used in comparing interrater reliabilities. (SLD)
