In the present Monte Carlo simulation study, the authors compared bias and precision of 7 sampling error corrections to the Pearson r[superscript 2] under 6 x 3 x 6 conditions (i.e., population ρ values of 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9, respectively; population shapes normal, skewness = kurtosis = 1, and skewness = -1.5 with kurtosis = 3.5;…

In this study the authors investigated the use of 5 (i.e., Claudy, Ezekiel, Olkin-Pratt, Pratt, and Smith) R[squared] correction formulas with the Pearson r[squared]. The authors estimated adjustment bias and precision under 6 x 3 x 6 conditions (i.e., population [rho] values of 0.0, 0.1, 0.3, 0.5, 0.7, and 0.9; population shapes normal, skewness…

Investigated the patterns of statistical usage and reporting in 756 articles published in the "American Educational Research Journal" (AERJ) and the "Journal of Counseling Psychology" (JCP) over 10 years. Evaluated the analytic practices used. Also discusses changes that may be necessary to improve statistics in behavioral research. (SLD)

Asserts that editors should declare their expectations publicly and expose the rationale for editorial policies to public scrutiny. Supports effect size reporting and the reporting of score reliabilities. Argues against stepwise methods. Also discusses the interpretation of structure coefficients and the use of confidence intervals. (SLD)

The use of three aspects of recommended practice (language use, replicability analyses, and reporting effect sizes) was studied in quantitative reports in "The Journal of Experimental Education" (JXE) for the academic years 1994-95 and 1995-96. Examples of both errors and desirable practices in the use and reporting of statistical significance…

Canadian and American education students rated each of four teacher types in terms of 24 characteristics. The ratings were factor-analyzed and the teacher types arrayed along the four resultant-principal components. Dissonance theory suggests that findings have implications for teacher education and for student ratings of teachers. (Author)

Advantages and disadvantages of three analytic methods are discussed. A hypothetical data set is employed to make the discussion complete. It is suggested that commonality analysis can be usefully employed in research studies in education, particularly when aptitute-treatment interaction studies are involved. (Author/LMO)

A detailed study of the nature of educators' education-related attitudes is presented. Results suggest that Kerlinger's theoretical principle that social attitudes are dualistic may need to be qualified when the attitudes studied involve the vital roles of subjects. (Author/GK)

The study investigated personality and aptitude correlates of test-wiseness skills, which were measured by assessing the subject's ability to utilize deductive reasoning and item cues. Personality factors and aptitude were measured. Results indicated that cognitive variables have more power to predict test-wiseness scores than do personality…

The comparability of seven sets of factor structure studies reported in previous research with the Bem Sex-Role Inventory was evaluated. The inventory's primary factors were reproduced in the studies, although the masculine scale was somewhat less invariant than was the feminine counterpart. (SLD)

This paper presents a method which can be used to obtain evidence that the concepts rated on semantic differential scales are appropriate for given study. An analysis of six semantic differential concepts, as perceived by 168 graduate education students, is presented; variations of the method are discussed. (Author/GSK)

Adequacy coefficients can be derived by calculating the cosines of the angles between factors' actual and theoretically expected locations within factor space. The use of adequacy coefficients during instrument development is discussed. The development of an instrument to measure thinking interests provides a heuristic framework for the…

Monte Carlo methods were used to evaluate the degree to which canonical function and structure coefficients may be differentially sensitive to sampling error. For each of 64 research situations, 1,000 random samples were drawn. Both sets of coefficients were roughly equally influenced; some exceptions are noted. (SLD)

Three criticisms of conventional uses of structural significance testing are elaborated; and alternatives for augmenting statistical significance tests are reviewed, which include emphasizing effect size, evaluating statistical significance in a sample size context, and evaluating result replicability. Among ways of estimating result…
