In this study, smoothing and scaling approaches are compared for estimating subscore-to-composite scaling results involving composites computed as rounded and weighted combinations of subscores. The considered smoothing and scaling approaches included those based on raw data, on smoothing the bivariate distribution of the subscores, on smoothing…

The kappa coefficient and the chi square statistic are used as indices of agreement between two judges' ratings of a set of stimuli on a nominal scale. In this article, the logic of these indices is extended to weighted multi-way cases. (Author/JKS)

Four methods for combining several scores of tests given the same individual are discussed: (1) weighted standardized scores; (2) percentile rank methods; (3) the principal components approach; and (4) the optimal weights method. The optimal weights method is recommended because of its simplicity. (SLD)

A rational approach to standard transformed scores which always results in the numerical to letter grade correspondence for any chosen hypothetical grade distribution model is developed. (Author/LMO)

The G index of agreement does not permit the use of various weights for its various items. The weighted G index described here, make it possible to use unequal weights. An example of the procedure is provided. (Author/JKS)

Estimates for the variances of empirically determined scoring weights are given. It is also shown that test item writers should write distractors that discriminate on the criterion variable when this type of scoring is used. (Author)

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…

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)

Data from five separate samples were weighted using the vertical percent method (England) and the rare response method (Telenson, Alexander, and Barrett) to investigate their relative effectiveness for scoring biographical information blanks. Vertical percent scoring yielded significant validity coefficients for all samples, while rare response…
