Determining the Length of Multiple Choice Criterion-Referenced Tests When an Answer-Until-Correct Scoring Procedure Is Used.
Wilcox, Rand R. – Educational and Psychological Measurement, 1982
When determining criterion-referenced test length, problems of guessing are shown to be more serious than expected. A new method of scoring is presented that corrects for guessing without assuming that guessing is random. Empirical investigations of the procedure are examined. Test length can be substantially reduced. (Author/CM)

Analyzing the Distractors of Multiple-Choice Test Items or Partitioning Multinomial Cell Probabilities with Respect to a Standard.
Wilcox, Rand R. – Educational and Psychological Measurement, 1981
A formal framework is presented for determining which of the distractors of multiple-choice test items has a small probability of being chosen by a typical examinee. The framework is based on a procedure similar to an indifference zone formulation of a ranking and election problem. (Author/BW)
