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)

Monte Carlo results were used to evaluate procedures for discriminating between groups. A multiple testing version of Hotelling's T-squared and the Bonferroni procedure were most powerful for detecting at least one true difference, depending on conditions examined. A multiple Bonferroni procedure was superior in power for detecting all true…

The canonical correlations and canonical loadings indicated the existence of a single dominant factor between the primary and middle grade data. This factor was interpreted as general scholastic ability. (Author)

Analyses of General Educational Development (GED) ratings of U.S. jobs illustrate the estimation of components of variance and covariance, univariate nd multivariate generalizability coefficients, and canonical coefficients. GED scales, ranging from one to six points, measure reasoning, mathematics, and language abilities needed to perform various…

With the development of refined theory and increased measurement sophistication in family research, multidimensional concepts and multiple indicators are appearing in the literature. This paper provides a nonmathematical introduction to canonical correlation analysis and three empirical examples that demonstrate the technique's applicability in…

Presents a study that utilized a new measure of response inhibition and attention with a sample of boys (n=50) diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) and a control group of age-matched boys (n=50). Reveals that the ADHD boys performed more poorly than the control boys. Includes references. (CMK)

Addresses the question of whether use of student samples jeopardizes the validity of research. Examines the distinction between univariate and multivariate relationships in a study of identification with Diana, Princess of Wales. Shows that although the estimates of univariate values differed across three samples, the multivariate relationships…

Focuses on the importance of teaching graduate students more about research. Discusses the content of a counseling psychology research seminar in which the students read articles from the "Journal of Counseling Psychology." Included readings on research design and methodology and multivariate statistical procedures. (CMK)

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…

The link between learning style and Jungian psychological type was assessed using 492 ninth graders attending a metropolitan high school. Various learning style inventories were administered. Canonical correlation procedures indicated the presence of 2 bipolar learning preferences characterized by a reflective learner/active learner…

Canonical analysis of two convex polyhedral cones involves looking for two vectors whose square cosine is a maximum. New results about the properties of the optimal solution to this problem are presented. The convergence of an alternating least squares algorithm and properties of limits of calculated sequences are discussed. (SLD)

High school physics students (n=41) were exposed to both massed and distributed practice on two different physics topics. Results suggest that using distributed practice in high school physics classrooms can lead to higher student achievement. (11 references) (Author/MKR)

A two-stage approach based on the rationale of maximum likelihood and generalized least-squares methods is developed to analyze the general structural equation model for continuous and polytomous variables. Some illustrative examples and a small simulation study (50 replications) are reported. (SLD)

Observes the impact of gender and status on the communication of 26 same-sex and 13 mixed-sex dyads of college students. Suggests that differences in the use of certain linguistic features may be more a result of a power differential than of gender. Other characteristics of the speaker, however, must also be considered. (CJS)

Examined the attitudes of a sample of 95 high school students concerning the relationship between education, intelligence, background, and occupational attainment. Advises that less advantaged students be made aware of occupational opportunities, and of the distinction between school learning and on-the-job performance. (DM)
