Lower Bounds for the Reliability of the Total Score on a Test Composed of Nonhomogeneous Items: I. Algebraic Lower Bounds
Jackson, Paul H.; Agunwamba, Christian C.
Psychometrika, 42, 4, 567-78, Dec 77
Finding and interpreting lower bounds for reliability coefficients for tests with nonhomogenous items has been a problem for psychometricians. This paper presents a mathematical formula for finding the greatest lower bound for such a coefficient. (Author/JKS)
