Describes a study of recent business school graduates that examined whether there are significant differences in the management skills learned when different teaching methods are employed. Highlights include a ranking of managerial skills by importance; a discussion of the value of educational programs; and a comparison of teaching methodologies.…

Describes a study that recorded the type and severity of body movements of 79 boys with ADHD (attention deficit hyperactivity disorder) and 67 non-ADHD boys while playing a computer video game. Results of multivariate analysis of variance showed no statistically significant differences in body movements between ADHD and non-ADHD boys. (Author/LRW)

This article compares two methods for analyzing small sets of repeated measures data under normal and non-normal heteroscedastic conditions: a mixed model approach with the Kenward-Roger correction and a multivariate extension of the modified Brown-Forsythe (BF) test. These procedures differ in their assumptions about the covariance structure of…

This study examined two conceptions of perfectionism in relation to interpersonal problems. Two hundred and seventy-nine undergraduate participants completed the Almost Perfect Scale-Revised (APS-R) and the Dyadic Almost Perfect Scale (DAPS). The authors used empirically derived discriminant functions (APS-R) and cluster analysis (DAPS) to…

This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion…

Background: The marked degree of heterogeneity in persons with developmental dyslexia has motivated the investigation of possible subtypes. Attempts have proceeded both from theoretical models of reading and the application of unsupervised learning (clustering) methods. Previous cluster analyses of data obtained from persons with reading…

Recent research indicates that adjudicated female youth have higher rates of mental health problems and histories of trauma exposure and abuse relative to adjudicated male youth. These differences are important for gender-specific assessment, intervention, and management strategies. We replicated a subtyping strategy for adjudicated female youth…

The attitudes of teachers of the middle grades (grades 6, 7, and 8) are compared, along various dimensions, to those of elementary and high school teachers in this study. The sample consisted of 73 graduates of the University of Cincinnati teacher education programs employed as teachers in the metropolitan Cincinnati (Ohio) area. All of the…

The representation of multivariate data by icons is discussed. The factorial sun is suggested as superior to the commonly used snowflake or sun icons and as better representing the values of the different variables and their correlational structure. Two experiments with 60 college students demonstrate the factorial sun's superiority. (SLD)

Two recent indices of fit, the Relative Noncentrality Index (RNI) (R. P. McDonald and H. W. Marsh, 1990) and the Comparative Fit Index (P. M. Bentler, 1990), are shown to be algebraically equivalent in most applications, although one condition in which the RNI may be advantageous for model comparison is identified. (SLD)

Cluster analyses using the Almost Perfect Scale--Revised (APS-R; R. B. Slaney, M. Mobley, J. Trippi, J. Ashby, & D. G. Johnson, 1996) yielded 3 clusters that represented adaptive perfectionists, maladaptive perfectionists, and nonperfectionists. Maladaptive perfectionist scores were strongly correlated with self-critical depression, but not…

Seven data sets (namely, clinical data on children) were subjected to clustering by seven algorithms--the B-coefficient, Linear Typal Analysis; elementary linkage analysis, Numerical Taxonomy System, Statistical Analysis System hierarchical clustering method, Taxonomy, and Bolz's Type Analysis. The little-known B-coefficient method compared…

Through statistical analysis the brief attempts to add to discussion of complex issues involved in the closing by the federal/state/vocational rehabilitation system of over 31,000 cases of persons with legal blindness and other visual impairments during 1980. (MC)

Relationships among individual- and group-directed measures of leader behavior descriptions and five variables were examined using 54 law enforcement agency personnel associated with a large public university. Data on a questionnaire completed by participants during an interview were studied. Explicit consideration was given to multiple levels of…

Purpose: Our objective in this study was to compare Medicare costs of treating older adults with and without dementia in nursing home settings. Design and Methods: An expert panel established the dementia status of a stratified random sample of newly admitted residents in 59 Maryland nursing homes between 1992 and 1995. Medicare expenditures…
