An Application of Item Response Theory in the Comparison of Four Conventional Item Discrimination Indices for Criterion-Referenced Tests.

Shannon, Gregory A.; Cliver, Barbara A.

Journal of Educational Measurement, v24 n4 p347-56 Win 1987

Spearman correlations were computed between item response theory-derived information functions (IIFs) and four conventional item discrimination indices: phi-coefficient; B-index; phi/phi max; and agreement statistic. Correlations between the phi-coefficient and the IIFs were very high. Data were taken from a real estate licensing test. (Author/GDC)
