Six scoring methods for assigning weights to right or wrong responses according to various instructions given to test takers are analyzed with respect to expected change scores and the effect of various levels of information and misinformation. Three of the methods provide feedback to the test taker. (Author/CTM)

Ordinal response modes for multiple choice tests are those under which the examinee marks one or more choices in an effort to identify the correct choice, or include it in a proper subset of the choices. Two ordinal response modes: answer-until-correct, and Coomb's elimination of choices which examinees identify as wrong, were analyzed for scoring…

Six different approaches to scoring test data, including number right, correction for guessing, and answer-until-correct, were investigated using Monte Carlo techniques. Modes permitting multiple response showed higher internal consistency, but there was little difference among modes for a validity measure. (JKS)

Students in an introductory college course (n=275) responded to equivalent 20-item halves of a test under number-right and formula-scoring instructions. Formula scores of those who omitted items overaged about one point lower than their comparable (formula adjusted) scores on the test half administered under number-right instructions. In contrast,…
