An Empirical Assessment of the Mantel-Haenszel Statistic for Studying Differential Item Performance.

Raju, Nambury S.; And Others

Applied Measurement in Education, v2 n1 p1-13 1989

The effects of number of score groups and inclusion/exclusion of the studied item were examined in an empirical evaluation of the Mantel-Haenszel technique (MHT), using 3,795 elementary school students who took the SRA vocabulary test. Inclusion of four or more score groups yielded stable alpha estimates with the MHT. (SLD)
