A Computer program written in FORTRAN IV is presented which will create a population of desired size with marginally normal score vectors manifesting any desired centroid and covariance matrix. Uses and documentation are provided. (Author)

Many data analysis problems in psychology may be posed conveniently in terms which place the parameters to be estimated on one side of an equation and an expression in these parameters on the other side. A rule for improving the rate of convergence of the iterative solution of such equations is developed and applied to four problems. (Author/RC)

The authors describe a computer program which can provide feedback to group members helping them to acquire better self-perception and interpersonal awareness. The program has been successfully used with various kinds of groups. (SE)

Illustrated is the power of multidimensional scaling in reducing a complex set of proximity measures to a simple geometric picture that shows the relationship among data objects. Methods are discussed for determining the number of dimensions needed to represent a set. (Author/DEP)

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)

A quantitative approach was used to identify factors relating to emotional adjustment in 84 dying patients. Emotional adjustment was influenced more by the patient's physical condition, by previous experiences with dying persons, and by interpersonal relationships. (Author)

This study tested the hypothesis that the domain of physical fitness could be defined by the four factors of upper body, trunk, leg, and cardiorespiratory strength and endurance. (JS)

This article reports a study of the influences on the choice of subject matter and teaching methods made by teachers of economics. (Editor)

The effects of initial practice teaching on the self-conceptions of 50 Monash University Diploma in Education students were measured over a pretest-posttest interval of five weeks. (Editor)

This study examined contextual and structural variables of 23 community, private, and agricultural colleges and technological institutes in Alberta and British Columbia. The Aston methodology employed discriminated structural differences in the four groups. (Author/WM)

Regression analysis is one of the more common analytic tools used by researchers. However, multicollinearity between the predictor variables can cause problems in using the results of regression analyses. Problems associated with multicollinearity include entanglement of relative influences of variables due to reduced precision of estimation,…

A constrained component analysis method, which bears a formal resemblance to the confirmatory factor analysis methods developed by K. G. Joreskog (1969) and others, is presented. In confirmatory factor analysis, the constraints allow the testing of formally structural hypotheses within a model that is falsifiable, even in its "just…

Each of the four classic multivariate analysis of variance (MANOVA) tests of statistical significance may lead a researcher to different decisions as to whether a null hypothesis should be rejected: (1) Wilks' lambda; (2) Lawley-Hotelling trace criterion; (3) Roy's greatest characteristic root criterion; and (4) Pillai's trace criterion. These…

An experimental test battery (the Johnson O'Connor Research Foundation battery) designed to measure numerical facility was administered to 1,451 subjects at 12 testing centers across the United States over a 5-month period. Five work samples were included: (1) arithmetic; (2) counting backwards; (3) number reasoning; (4) rule learning; and (5)…

The initial form of the Coping with Death Scale consisted of 30 items designed to obtain responses arranged along a seven-point Likert-type scale. Each item on the scale was derived from personal responses of students who completed a death and dying seminar. The items appeared to fall into two categories: coping with self and coping with others.…
