Summary

This paper outlines a technique for differentially weighting options of a multiple choice test in a fashion that maximizes the item predictive validity. The rule can be applied with different number of categories and the "optimal" number of categories can be determined by significance tests and/or through the R2 criterion. Our theoretical analysis indicates that more complex scoring rules have: higher item validities, higher item variances, higher score variances, and are also likely to increase the interitem correlations and the test reliability. A plausible explanation for the apparent paradox of lack of improvement in the test validity, based on the relation between interitem correlations and item validities, is offered. (Author)
