Multiple regression processes are employed to assess the effect of student age on preclinical medical school achievement in the context of eight other predictor variables. Results indicate that student age fails to contribute to the explanation of preclinical achievement after the influence of the other variables is taken into account. (Author/CM)

A study used a combination of cross-sectional and longitudinal designs to assess the variables of curriculum, intelligence, socioeconomic status, and Career Maturity Inventory scores. The mixing of a multiple regression analysis approach to analysis of covariance with a convergence design proved to be a viable method. (SK)

The purpose of this study was to use multivariate techniques in a federally-regulated validation study, and compare the results obtained from zero-order correlations and multiple correlations with the results obtained using factor scores and canonical correlation. The subjects consisted of 51 applicants for the position of patrolman. (Author/CTM)

The American College Testing Program sought to determine whether metric education for adult consumers would result in more positive attitudes to metric conversion. Examining preopinion, pretest, posttest, post-opinion, and background data, the researchers found that simply teaching adults how to use the metric system does not significantly affect…

Discusses the use of pocket calculators for the computation of a line by the least-square-fitting method. The method is exemplified with a classical student experiment. (HM)

Data in Yarworth and Gauthier's article on student self- concept and participation in school activities (EJ 189 606) were reanalyzed by Walsh and Winne (TM 505 375). Yarworth and Gauthier's criticism of the reanalysis (TM 505 376) is answered. (GDC)

Three methods of estimating a model of school effects are compared: ordinary least squares; an approach based on the analysis of covariance; and, a residualized input-output approach. Results are presented using a matrix algebra formulation, and advantages of the first two methods are considered. (Author/GK)

Computer-based Monte Carlo methods compared the predictive accuracy upon replication of regression of five complete and four incomplete factor score estimation methods. Prediction on incomplete factor scores showed better double cross-validated prediction accuracy than on complete scores. The unique unit-weighted factor score was superior among…

Of 50 students taking a graduate course in multiple regression analysis at a particular university, they tended to use multiple regression in their dissertations. (Author/JKS)

Used locus of control, ability, sex, task selection, task structure, and recall in a regression model to predict affective response to type of instruction of 104 high school seniors. Results showed a main effect for recall, and interaction effects for recall x sex and recall x ability. References are listed. (Author/JEG)

A statistical framework for investigating various regression approaches to linear composites is presented in this monograph. The consequences of variance approaches for psychometric theory are discussed. (A six-page bibliography is appended). (JKS)

Among the variables considered, the best predictor of achievement in biology is the IQ of the students; the type of ninth-grade science course completed seems to have very little to do with subsequent performance in biology. (DS)

Investigates the relationship between employee performance with new technology and perceptual and communication factors. Finds strong correlational evidence that three aspects of employees' perceptions of a new technology's attributes and two types of messages affect their productivity levels with that technology.

A specially designed Life Goals Scale was administered to 303 university students (200 women and 103 men) to assess the relative importance of life goals and relationships. Results indicate that university students place a high value on heterosexual relationships and are willing to sacrifice most other goals for the relationships. (AF)

The aim of this study was to determine the relative potency of different student characteristics potentially salient to differentiating epistemological view. The student variables were demographic (major and sex), verbal ability, and learning style (four scales from the Inventory of Learning Processes). (Author/MLW)
