The answer-until-correct (AUC) procedure requires that examinees respond to a multi-choice item until they answer it correctly. Using a modified version of Horst's model for examinee behavior, this paper compares the effect of guessing on item reliability for the AUC procedure and the zero-one scoring procedure. (Author/CTM)

A scoring technique for true-false tests is presented. The technique, paired item scoring, involves combining two statements and having the student select one of the four resultants possible: true-true, false-true, true-false, and false-false. The combined item is treated as a multiple choice item. (Author/JKS)

Under the assumptions of classical measurement theory and the condition of normality, a formula is derived for the reliability of composite scores. The formula represents an extension of the Spearman-Brown formula to the case of truncated data. (Author/JAZ)

Two multitrait-multimethod studies were conducted to investigate the effects of two scoring formulas. The study demonstrates that tests of divergent thinking lack discriminant validity when scored in the usual manner. A percentage formula did enhance discriminant validity when originality ratings were subjectively determined. (Author/CTM)

Supports arguments against general use of change scores and recommends the Lord/McNemar estimates of true change. Provides a numerical example illustrating the reliability problem and the problem of the prediction of true change from various linear composites of initial and final measures. (Author)

Forty adolescent subjects with behavior problems at home or at school were administered the Woodcock Reading Mastery Tests. Subjects ranged in age from 12 to 18, and included 25 males and 15 females. The Passage Comprehension Test for each subject was rescored using three different ceiling criteria: (1) five errors in six consecutive responses,…

Compares various item option scoring methods with respect to coefficient alpha and a concurrent validity coefficient. Scoring methods compared were: formula scoring, a priori scoring, empirical scoring with an internal criterion, and two modifications of formula scoring. The empirically determined scoring system is seen as superior. (RC)

Findings regarding formats and scoring formulas for multiple-choice test items with more than one correct response are presented. Strong cluing effects in the Type K format, increasing the correct score percentage and reducing test reliability, recommend using the Type X format. Alternative scoring methods are discussed. (Author/CM)

Procedures for computing content validity and consistency reliability coefficients and determining the statistical significance of these coefficients are described. Procedures employing the multinomial probability distribution for small samples and normal curve probability estimates for large samples, can be used where judgments are made on…

Investigates the reliability and validity of scores yielded from a new scoring formula. (Author/DEP)

It has been shown that Guttman weighting of test options results in marked increases in the internal consistency of a test. However, the effect of this type of weighting on the structure of the test is not known. Hence, the purpose of this study is to compare the factor structure of Guttman-weighted and rights-only-weighted tests and to relate the…

Binary, probability, and ordinal scoring procedures for multiple-choice items were examined. In two situations, it was found that both the probability and ordinal scoring systems were more reliable than the binary scoring method. (Author/CTM)
