An Approximately Reproducing Scoring Scheme That Aligns Random Response and Omission.
Abstract
One formulation of confidence scoring requires the examinee to indicate as a number his personal probability of the correctness of each alternative in a multiple-choice test. For this formulation a linear transformation of the logarithm of the correct response is maximized if the examinee accurately reports his personal probability. To equate omits scores with choice scores, the transformation can be chosen so that the score is zero if the examinee indicates complete uncertainty. If this is done, the scoring function depends on the number of alternatives.
