This paper discusses the principles underlying discriminant analysis and constructs a simulated data set to illustrate its methods. Discriminant analysis is a multivariate technique for identifying the best combination of variables to maximally discriminate between groups. Discriminant functions are established on existing groups and used to…

The paper reviews a construct validation framework for research on the selection and evaluation of residents. The application of the proposed methodology to surgery residents is described. The need to measure non-cognitive and neuropsychological factors in addition to cognitive knowledge and technical ability is emphasized. (Author/MLW)

This longitudinal study across the primary grades examined whether there were patterns in feedback strategies parents provided to children's miscues during shared book reading, and whether parents changed their use of those strategies over time as their children's reading skills increased. Parents of normally developing beginning readers were…

Industrial culture focuses mainly on the production of "things"--of static objects. Knowledge, on the other hand, is constantly in flux, like a flowing stream. Conventional industrial notions lead policy makers to believe that the addition of a knowledge-based industry to an existing industrial base makes a knowledge economy. This is not the case.…

Using a national sample of 3,774 undergraduates, this study investigated the effect of involvement in the college experience on learning for students who were employed off campus. Students employed more than 20 hours per week off campus engaged with faculty and peers less frequently than other students on all variables except discussing ideas with…

In order to ease the academic and social transition, to forge a solid foundation for the rest of the academic career, and to increase the likelihood that students will persist through the second year and beyond, curricula and cocurricular programs are designed to meet the needs of first-year students and facilitate learning and development.…

Complex decision-making environments often demand that a range of alternative strategies be identified and compared for their shared value in achieving desired ends. Simple parametric statistical procedures such as analysis of variance and discriminant function analysis can be used in such situations to compare (using selected criteria) the value…

Two approaches of statistical testing are critically reviewed. A new approach, which is a hybrid of the two, is proposed. The new approach requires the researcher to think about the two types of potential inferential errors and an explicit alternative hypothesis of interest. (VM)

International student admissions in universities can be facilitated by multivariate statistical procedures. On the basis of existing data on student characteristics, predictions can be made regarding performance of applicants. These predictions consider personal variables, knowledge of English, and various indicators of academic performance.…

Describes the use of a simulated learning environment (SLE) as an instructional aid in teaching multivariate statistics, particularly inferential statistics. A prototype microcomputer-based SLE called MVWORLD developed at Drexel University for upper level statistics courses is explained, and implementing a statistics laboratory for multivariate…

Describes a study conducted at the Naval Postgraduate School to determine student attitudes toward various aspects of network-based instruction. Discusses Internet technology; Web-based education; online learning; learning styles; and results from Kolb's Learning Style Inventory, the Hidden Figures Test, and a number of multivariate procedures.…

This study analyzed the word-, sentence-, and passage-level demands of high-interest, low-level books in a manner consistent with an interactive model of reading comprehension. Cases consisted of three randomly selected passages from sixty different books. Cases were analyzed across five variables: high-frequency words, decodable words, sentences,…

We describe a principled way of imposing a metric representing dissimilarities on any discrete set of stimuli (symbols, handwritings, consumer products, X-ray films, etc.), given the probabilities with which they are discriminated from each other by a perceiving system, such as an organism, person, group of experts, neuronal structure, technical…

This paper defines, develops, and displays a mathematical modeling formulation for exploring decisions available to the higher educational administrator in evaluating discrete educational program budgets (instructional, service, and administrative) for possible future funding alternatives. Complex budget reduction strategies can be…

This is an exploratory study of the associations among parental warmth, peer support, gender, and emotional distress in a sample of 308 adolescents in the United States. Parental warmth was associated with less emotional distress, whereas turning to peers for support during family conflict was associated with more emotional distress. Gender…
