Effect of Sample Size, Number of Biased Items, and Magnitude of Bias on a Two-Stage Item Bias Estimation Method.

Miller, M. David; Oshima, T. C.

Applied Psychological Measurement, v16 n4 p381-88 Dec 1992

A two-stage procedure for estimating item bias was examined with six indices of item bias and the Mantel-Haenszel statistic. Results suggest that the two-stage procedure is not very useful when the number of biased items is small and bias magnitude is weak. (SLD)
