Scoring of multiple choice items by means of internal linear weighting

Abstract
Four scoring methods for multiple choice items were compared: number-right scoring, guessing correction, homogeneity analysis and weighting of choices according to their correlation with the number right score. The four methods were compared according to the validity, reliability and dimensionality of the resulting scores. Comparisons were based on simulated data, where the proportion of responses due to guessing and the discrimination power of options were controlled. The results showed an inferior performance of the guessing correction and a good performance of the proposed correlation-weighting, especially when traditional assumptions about multiple choice items were violated.
