Test Reliability and the Kuder-Richardson Formulas: Derivation from Probability Theory
Zimmerman, Donald W.
Educational and Psychological Measurement, 32, 4, 939-54, W 72
Although a great deal of attention has been devoted over a period of years to the estimation of reliability from item statistics, there are still gaps in the mathematical derivation of the Kuder-Richardson results. The main purpose of this paper is to fill some of these gaps, using language consistent with modern probability theory. (Author)
