A Monte Carlo Comparison of Ten Item Discrimination Indices.

Beuchert, A. Kent; Mendoza, Jorge L.

Journal of Educational Measurement, v16 n2 p109-17 Sum 1979

Ten item discrimination indices, across a variety of item analysis situations, were compared, based on the validities of tests constructed by using each of the indices to select 40 items from a 100-item pool. Item score data were generated by a computer program and included a simulation of guessing. (Author/CTM)
