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…

The effects of applying different methods of determining different sets of subscore weights on the composite score ranking of examinees were investigated. Four sets of subscore weights were applied to each of three examination results. The scores were from Advanced Placement (AP) Examinations in History of Art, Spanish Language, and Chemistry. One…

An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

A statistical comparison of Medical College Admission Test scores with National Board of Medical Examiners (NBME) Part I scores of one school's students supported simple averaging of subtest scores rather than weighting as a predictor of NBME Part I performance. Similar results were obtained using basic science course examination scores. (MSE)

This study empirically determined the optimizing weight to be applied to the Wrongs Total Score in scoring rubrics of the general form = R - kW, where S is the Score, R the Rights Total, k the weight and W the Wrongs Total, if reliability is to be maximized. As is well known, the traditional formula score rests on a theoretical framework which is…

In order to develop tools for use in the selection and vocational-educational guidance of U.S. Naval Academy midshipmen, three empirically-based scales, designed using the Strong Vocational Interest Blank (SVIB), were developed to predict three criteria: (1) disenrollment for academic reasons, (2) disenrollment for motivational reasons, and (3)…

Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)

The Statewide Assessment Program of the Florida State Department of Education is responsible for measuring student achievement and disseminating the assessment results. One dimension of this effort has been the development of predicted or adjusted school scores. These scores are based on several factors which are related to achievement. Among…
