Recent studies are examined for methodological adequacy in establishing dimensions of individual differences in information-processing abilities, and the theoretical problems involved in inferring psychological processes from individual difference dimensions. Methodological inadequacies include use of small samples, questionable procedures in…

Application of the Kruskal-Wallis test to survey research problems is discussed as an alternative for the business education researcher in testing questionnaire response differences among three or more independent groups. Problem illustrations and a computer program are included. (MF)

The purpose of this study was to determise the relative loss in statistical power of traditional methods of analysis when response-shift bias is present. Five methods of analysis (posttest scores only; postminus pretests; postminus retrospective pretest; postcovaried by pretest; postcovaried by retrospective pretest) were compared. (Author/BW)

The author discusses a common error in marriage research, i.e. use of a control group. Single scores which are correlated require no randomized control group. Two arrays of scores which are correlated generally require a randomized control group. (Author/HMV)

Presents a brief, quick-reference check list of methodological errors, fallacies, mistakes, and instances of out-and-out trickery that are found in recent well-known studies of IQ, IQ heritability, and race differences, focusing primarily upon the works of psychologist Jensen, Herrnstein, Eysenck, including selected works of William Shockley and…

In 1987 the U.S. Census Bureau created a universe of private elementary and secondary schools for the National Center for Education Statistics (NCES). This universe has been updated every 2 years through list frame updating and area frame updating. For the list frame updating, lists of private schools are obtained from various associations around…

Because of limitations on research controls, research designs in postsecondary education are often complex and can involve many independent and potentially confounding variables. What is needed to adequately address such research questions is a flexible and powerful data-analytic approach, and the general linear regression model is recommended.…

Discusses theoretical and methodological problems relating to the comparison of test results of individuals and groups with differing cultural backgrounds. Develops a statistic by which deviance of score patterns can be quantified and which indicates whether a person's score can be compared with the scores in a specific group. (Author/GC)

Discusses the relationship between changes in delinquency prevalence over time and prediction error. Data from a 21-year British longitudinal study exemplify the formal relationships that are derived. Results indicate statistically, as prevalence increases, a relative increase in false negative errors and a decrease in false positive errors…

With even the simplest bivariate regression, least-squares solutions are inappropriate unless one assumes a priori that reciprocal effects are absent, or at least implausible. While this discussion is limited to bivariate regression, the issues apply equally to multivariate regression, including stepwise regression. (Author/CTM)

Suggests that dominance can be defined as asymmetry in predictability in social variables of importance, and bidirectionality as symmetrical predictability. Procedures which address the concepts of cyclicity within a person and synchronicity between people and which assess asymmetry and symmetry in social interaction are discussed. (Author/RH)

It is shown that using formulae for the estimation of sampling errors based on simple random sampling, when a design actually involves cluster sampling, can lead to serious underestimation of error. Jackknife and balanced repeated replication are recommended as techniques for dealing with this problem. (Author/CTM)

The "history of education" should no longer be considered an independent field for research and teaching. Many important questions in the history of ideas have been and continue to be numberically based, and require quantitative analysis to be answered. Revisionism in history has often involved the use of a quantitative methodology. (Author/JM)

Discusses quasi-experimental and experimental research methodologies for investigating the relationships among teacher behavior, teacher competencies, student achievement, and student attitude outcomes. (MLH)

Concludes "that the one seemingly serious effort of Baltes and Schaie to contest the points of the Horn-Donaldson criticisms only brings us around to the same sad conclusion: that no matter how one looks at the Schaie data, it suggests that, on the average, there is age decline in many important abilities of intelligence."
