Logical Versus Empirical Estimates of Item Difficulty
Quereshi, M. Y.; Fisher, Thomas L.
Educational and Psychological Measurement, 37, 1, 91-100, Spr 77
Logical estimates of item difficulty made by judges were compared to empirical estimates derived from a test administration. Results indicated substantial correspondence between logical and empirical estimates, and substantial variation among judges. Further, the more elaborate the system used by judges to make estimates, the more accurate the estimates. (Author/JKS)
