The use of Guttman weights in scoring tests is discussed. Scores of 2,500 men on one subtest of the CEED-SAT-Verbal Test were examined using cross-validated Guttman weights. Several scores were compared, as follows: Scores obtained from cross-validated Guttman weights; Scores obtained by rounding the Guttman weights to one digit, ranging from 0 to…

A sample of 153 male police officers were subjects in a test validation study with two objectives: (1) to compare reliability estimates of a 16-item objective achievement examination scored by the conventional items right formula and by four different procedures; and (2) to obtain comparative concurrent validity coefficients of scores arising from…

Two conventional scores and a weighted score on a group test of general intelligence were compared for reliability and predictive validity. (Editor)

A hand-scoring system for a three-level confidence-marking scheme for short answer and multiple-choice tests is described. The scoring system is for a test where the student is asked to indicate for each answer whether the probability of his being correct is more than 1/2 (sure), 1/2 (neutral), or less than 1/2 (guess). The effect of the system is…

Option weighting is an alternative to increasing test length as a means of improving the reliability of a test. The effects on test reliability of option weighting procedures were compared in two empirical studies using four independent sets of items. Biserial weights were found to be superior. (Author/CTM)

The reliabilities yielded by several differential option weighting scoring procedures were compared among themselves as well as against conventional testing. It was found that increases in reliability due to differential option weighting were a function of inter-item correlations. Suggestions for the implementation of differential option weighting…

This article evaluated criticisms by Stevens and Aleamoni (1986) of an article by Gardner and Erdle (1984) on aggregation using either raw or standard scores. It was demonstrated that their criticisms were unfounded. (Author)

The long-standing clinical lore which holds that a discrepancy between Wechsler-Bellevue Verbal-Performance Scale weighted scores is a more sensitive sign of lateralized brain damage than a discrepancy between Verbal-Performance Scale IQ is investigated. The results do not support the clinical lore. (Author/AL)

Presented is a personal computer computer-analysis system to help the consumer decide which microcomputer best suits his needs. (KC)

A strategy is described for comparing and weighting student marks on separate performance elements on the basis of statistical analysis and teacher judgment. Differences between nominal and effective weightings are discussed. (MSE)

In many countries, an athlete's performance at sporting competitions is often used as part of the selection criteria for entry into college. These criteria could be biased depending upon the procedures utilized by the authorities in a particular country. The purpose of this study was to calibrate, by using the Rasch rating scale model, the…

This article describes key concepts, reviews empirical findings, and discusses important issues related to the use of subjective importance ratings and importance weighting. The review of empirical findings focuses on weighting achieved via the multiplicative model and on 3 areas in which weighting is commonly used: quality of life, self-esteem,…
