The Mantel-Haenszel (MH) procedure attempts to identify and quantify differential item performance (item bias). This paper summarizes the MH statistics, and identifies the parameters they estimate. An equivalent procedure based on the Rasch model is described. The theoretical properties of the two approaches are compared and shown to require the…

To justify its labor force quality requirements, the Army sought to demonstrate an empirical link between Armed Forces Qualification Test (AFQT) scores and soldier performance. The first data set contained written and hands-on tests on several weapons systems from the Army's training schools. The second data set used the Skill Qualifications Tests…

Much of the scientific community has believed that temperament variables could not be included in batteries of tests to predict job performance because no generalized principles could be discerned from the results. For Project A, a major Army project on the prediction of job performance, a temperament inventory was developed and implemented. This…

Findings from research studies that use the Defining Issues Test (DIT), a test of moral judgment development, are described. These findings are relevant to three major questions in higher education research: (1) the question of student outcomes (i.e., what does college experience do for and to people?); (2) the question of the relevance and…

A prediction equation for teacher morale was developed from the responses of 236 teachers in a large school system in Mississippi. The Supervisory Conference Rating (SCR) was used to measure teachers' perceptions of the supervisory conference following observation by the principal. The Zones of Indifference of these teachers were measured with the…

A 13-item adult risk taking scale was selected by factor analysis and internal reliability testing from 25 items administered to 270 urban adults (56% Black; 33% White; 11% Hispanic/other) stratified by socioeconomic status. Chronbach's alpha equaled 0.77. Five items refer to risk of injury, five to risk of illness, one to gambling, and two to…

Recent research suggests that alcoholic inpatients' performance on neuropsychological tests is predictive of their drinking status following discharge from alcohol rehabilitation programs, although no single test itself has been predictive of relapse. This study seeks to develop a ecologically relevant memory test that would predict relapse and…

The United States Employment Service (USES) Specific Aptitude Test Battery (SATB) for Carpenter is evaluated from three points of view: (1) technical adequacy of the research; (2) fairness to minorities; and (3) usefulness of the battery to United States Employment Service staff and employers in selecting individuals for Carpenter positions.…

For over 50 years, the overwhelming weight of evidence has been that subjects are able to make use of partial information when responding to multiple-choice items. The subject chooses the alternative which has given rise to the lowest mismatch, except that if this minimum mismatch is larger than some threshold, the question is left unanswered.…

A study of whether perceptual processes of children can be viewed within a structuralist frame of reference and whether the concept of the group of transformations and related notions can be used to formulate perceptual phenomena and to predict experimental results. (Author/CS)

The paper describes instruments for determining preferences of consumers for selected product characteristics associated with furniture choices--specifically style, color, color scheme, texture, and materials--and the procedures for administration of those instruments. Results are based on a random sampling of public housing residents. (Author/MW)

The study reported here involved a search of non-academic variables to identify correlates of grades in an attempt to better predict academic success for black students; all subjects were black freshmen entering the University of Maryland in September, 1968. (Author/JM)

The concept of creativity is present in the thinking of all cultures. The idea of bringing new order out of non-order and new form out of the formless is basic to the concept of creativity. Despite the efforts of numerous researchers, defining giftedness or creativity appears to be a timeless problem. Presently there is still no universally…

Investigated the relationship of the ITPA subtests to measures of academic performance (i.e., the California Achievement Test). Subjects were 137 nine-year old children. Results failed to support the hypothesis that psycholinguistic abilities, except those which contribute to the Grammatic Closure subtest, are related to academic proficiency.…
