Researchers are becoming increasingly aware of the advantages of using multiple regression as opposed to analysis of variance (ANOVA) or analysis of covariance (ANCOVA). Multiple regression is more versatile and does not force the researcher to throw away variance by categorizing intervally scaled data. Polynomial regression analysis offers the…

The State of Pennsylvania, in an effort to determine how education relates to jobs, undertook a study of what happens to its graduates. The author analyzes the findings and draws some conclusions. (Author)

Purpose of this paper is to report the level of power for recent statistical tests reported in the AERJ and to propose alternative reporting schemes relative to hypothesis testing to include power and effect size. (Author)

The Little Jiffy" consists of principal components analysis and varimax rotation of all components with eigenvalues greater than one. (DG)

Analysis of 230 major articles in the "Journal of Medical Education" shows 91 percent of those reporting medical education research had less than a 50-50 chance of detecting a small treatment effect. Similar low statistical power was found in other disciplines. Guidelines for reporting research are provided. (MSE)

Presents a two-part analysis of the note on Proposition 20. Findings suggest that environmental concern may be more broadly distributed across different socioeconomic and political strata of our society than previous investigators have asserted. (Author/MA)

The authors examine the special educator's plight in translating laboratory findings into classroom practice, in terms of the possible ungeneralizability of the experimental outcomes. (Author/PHR)

A two-year study of learning disabilities found in association with French immersion programs indicates that children encountering difficulty in primary French immersion programs have a specific learning disability characterized by a pattern suggesting a maturational lag in the temporal lobe regions of the brain. (JMF)

Presents in full the questionnaire sent to member institutions of the American Society for Engineering Education to collect data on engineering education and research for the school year 1975-76. (MLH)

Investigates the discriminant validity of a measure of attitudes toward male roles, the Male Role Attitude Scale, using data from the 1988 National Survey of Adolescent Males. Results support the argument that attitudes toward male roles are conceptually different from other gender-related attitudes. (SLD)

Examines assumptions underlying the employment of group means in communication research. Suggests a sample mean cannot be assumed to be a "good" statistic when the response vector represents different individuals' outcomes versus different outcomes of an individual. Notes implications for communication research. (SR)

Selecting a statistical framework for a behavioral study has profoundly different results than does a linguistically framed research strategy. The linguistic strategy overcomes many limitations inherent in statistical strategies and offers more meaningful results. Inferential statistical studies often discuss how the findings "explain" the results…

This study evaluated a "substantively driven" method for scoring NAEP writing assessments automatically. The study used variations of an existing commercial program, e-rater[R], to compare the performance of three approaches to automated essay scoring: a "brute-empirical" approach in which variables are selected and weighted solely according to…

The paper is a critique of the traditional mode of interpreting factor analyses; it is not a criticism of factor analysis per se. Instead, the author proposes a statistical procedure based upon stepwise regression (SRP). The traditional mode focuses on the largest factor loadings (FL). A factor is both described and named by these heavily weighted…

Discusses the format, grading procedures, and student reaction to two undergraduate engineering courses taught by programed instruction. Statistical analysis shows that the programed instruction resulted in higher and more uniform student achievement than did the conventional instruction in the same subject area. (MLH)
