A study assessed the predictive validity of two substantially different instruments (a questionnaire or a philosophy statement) which may be used to predict critics' ballot behavior in Cross Examination Debate Association (CEDA) debate. Questionnaires were distributed to 29 debate tournaments across the United States for completion by critics…

A study was done at Panhandle State University (Oklahoma) examining whether high school grade point averages or ACT (American College Testing) scores provided a better predictor of freshman academic success. Study procedures included a review of the literature, meetings with the academic vice president and five deans, as well as examination of…

A statistical model for investigating predictive validity at highly selective institutions is described. When the selection ratio is small, one must typically deal with a data set containing relatively large amounts of missing data on both criterion and predictor variables. Standard statistical approaches are based on the strong assumption that…

This bibliography includes 35 reports of research, dated from 1978 to 1983, on the new Medical College Admission Test (MCAT). These reports consist primarily of studies published in professional journals or presented as papers at professional meetings. No effort was made to screen the studies for methodological adequacy or other measures of…

This study was conducted to determine the strength of the relationship between handicapped students who are mainstreamed into regular vocational education programs as a result of an evaluation recommendation and their retention in that program, as opposed to students who are enrolled without this recommendation. An individualized follow-up study…

This research indicates that the Ertl Neural Efficiency Analyzer is not yet out of the developmental stage. (IRT)

Male infant vocalizations were studied as a function of age. (JMB)

The study evaluates a test of occupational information administered to a national sample of 5000 young men in 1966, as part of the National Longitudinal Surveys of employment behavior. The measurement instrument is judged to exhibit desirable characteristics in terms of internal consistency reliability, discriminatory power, and level of…

The predictive validity and factor structure of the ABC Inventory were analyzed by comparing scores obtained by preschoolers on this test with scores on the Metropolitan Reading Test. The correlational and factor analyses results reveal significant empirical and conceptual relationships between the two tests. (Author/PC)

Psychologists and psychiatrists are regularly used during civil commitment and other hearings to prognosticate dangerousness for the courts. In this process, the judiciary has shown almost complete deference to the recommendations of forensic specialists despite a number of early studies that did not support a clinician's ability to predict…

An alternative definition has been developed of the delta scale of item difficulty used at Educational Testing Service. The traditional delta scale uses an inverse normal transformation based on normal ogive models developed years ago. However, no use is made of this fact in typical uses of item deltas. It is simply one way to make the probability…

The behavior of two real-time computer simulation models of melody recognition was compared with the performance of human subjects in this study. One of the models, INT1, recognized melodies by comparing specific intervals with stored intervals. The other model, CONT1, performed by comparing the contour of the stimulus melody with an array of…

Quality of performance data yielded by subjective judgment is of major concern to researchers in performance appraisal. However, some confusion exists in the analysis of quality on ratings obtained from different rating scale formats and from different raters. To clarify this confusion, a study was conducted to assess the quality of judgmental…
