Validity of Approximation Techniques for Detecting Item Bias.

Shepard, Lorrie A.; And Others

Journal of Educational Measurement, v22 n2 p77-105 Sum 1985

The purpose of this research was to recommend an item bias procedure when the number of minority examinees is too small to use preferred three-parameter item response theory (IRT) methods. The chi-square, Angoff delta-plot, and pseudo-IRT indices were compared with both real and simulated data. (Author/DWH)
