From 13 objective interview items, five with adequate response variability were studied to determine if they would improve the validity of a verbal ability selection test in predicting work performance of 181 psychiatric aide trainees. In a multiple regression analysis, the verbal test correlated .27 with the weighted composite rating score.…

Prior standardization of scores when an aggregate score is formed has been criticized. This article presents a demonstration of the effects of differential weighting of aggregate components that clarifies the need for prior standardization. The role of standardization in statistics and the use of aggregate scores in research are discussed.…

Study was designed to provide some indication as to whether the gain in test reliability from confidence scoring results from relevant or irrelevant sources. If the increase in reliability is the result of a gambling response style, it is conceivable that validity could actually decrease even though reliability is increased. (Authors/CB)

Five weighting methods for combining multiple criteria into a single composite were evaluated on 117 bank tellers. Four of the five methods (management, weights, equal weights, unit weights and factor weights) yielded nearly identical results. The fifth method (canonical weights) correlated almost zero with the other methods. (Author/PN)

The merits of double exponential smoothing are discussed relative to other types of pattern-based enrollment forecasting methods. The basic assumptions and formulas for its use are outlined. The difficulties associated with selecting an appropriate weight factor are discussed, and the potential effect on prediction results is illustrated.…

This article presents the initial methodology involved in the construction of a self-report instrument of delinquent behavior, as well as the comparison of 10 frequency and seriousness weighting schemes. Results indicate that the inclusion of weighting schemes does not strengthen the instrument or add to its applicability. (Author)

Factor scale scores are sometimes used as weights to create composite variables representing the variables included in a factor analysis. If these composite variables are then used to predict some dependent variable, serious theoretical and methodological problems arise. This paper explores these problems and suggests strategies for circumventing…

This study was designed as a reconsideration of the weights used in evaluative decisions made with regard to research proposals submitted for funding at a major state university. The specific objective of the study was to determine whether the actual weights for components used in the evaluation of the proposals differed from a priori weights…

A review of cross-validation shrinkage formulas is presented which focuses on the theoretical and practical problems in the use of various formulas. Practical guidelines for use of both formulas and empirical cross-validation are provided. A comparison of results using these formulas in a range of situations is then presented. The result of these…

A procedure for estimating the degree to which a subtest uniquely contributes to total test performance is presented and discussed. Uniqueness analysis may be appropriately applied to any composite measurement instrument such as a multipart test or a multitest battery to assess the unique contribution of each component to the total test. The…

Many problems in the areas of test interpretation and educational assessment are causing difficulties for educators. On one hand the public and legislators are requesting more state testing programs and assessment programs, while on the other, educators realize the problems concerning testing and test interpretation. Difficulties arise when tests…

Factor loadings, used directly or as the basis of binary values, are not appropriate as weights to produce component scores from a rotated solution. A series of examples showing the results of an incorrect measurement of components is given. Several correlation matrices were taken from books on factor analysis and multivariate analysis. Each…

This paper discusses the importance of criteria in the evaluation of a teacher by his students and proposes a method of representing the results of the questionnaire in the form of one weighted average. The following points, emphasized in the construction of the questionnaire, are elaborated: a) the characteristics of a good teacher; b) the…

It is argued that a major failing of most measures of self-esteem is that they do not take into account the value system of the individual subject. A method of measuring self-esteem is proposed based upon self-ratings in life areas, and the importance of those areas to the subject. (Author/JAC)

This paper presents an algorithm for determining the number of items to measure each objective in a criterion-referenced test when testing time is fixed and when the objectives vary in their levels of importance, reliability, and validity. Results of four special applications of the algorithm are presented. (BS)
