Lower Bounds for the Reliability of the Total Score on a Test Composed of Non-Homogeneous Items: II. A Search Procedure to Locate the Greatest Lower Bound

Woodhouse, Brian; Jackson, Paul H.

Psychometrika, 42, 4, 579-91, Dec 77

Finding and interpreting lower bounds for reliability coefficients for tests with non-homogeneous items has been a problem for psychometricians. A computer search procedure is developed for locating such a lower bound in a variety of settings. (Author/JKS)
