Describes a variety of relatively simple procedures for the modification of instruments to reduce cultural bias in research and to enhance the overall quality of industrial education research efforts. (SK)

A popular abbreviated version of the Marital Conceptualization Scale (MCS) was administered along with other measures of conventionality to 181 married couples. Correlational analysis failed to confirm the construct validity of the MCS as defined by the instrument's author. The investigators proposed renaming the response set "marital social…

Discussed problems and deficiencies in past research on clinical diagnosis, pertaining to sampling problems with regard to clinical subjects studied, adequacy of control groups, base rates, clinical versus statistical significance, lack of cross-validation, and problems due to reliance on inadequate schemes of classification. Future research is…

The choice of the clustering method, the similarity measure, the computer program, and the procedure for estimating the number of clusters should be clearly specified in any journal article using cluster analysis. Adequate evidence of a cluster solution's validity should be provided before the solution is published. (Author)

Comments on a journal article that suggests that educational statistics may be compared even in cases where different experimental units are used in the analyses. (MLH)

Views intercoder reliability as a sampling problem for content analyses. Develops a formula for generating sample sizes needed to have valid reliability estimates. Suggests steps for reporting reliability. (TB)

Criticizes the application of the statistical procedures of the population-genetic approach within evolutionary biology to the study of psychological development. Argues that the application of the statistical methods of population genetics--primarily the analysis of variance--to the causes of psychological development is bound to result in a…

Argues that Gottlieb rejects population sampling and statistical analyses of distributions as he proposes that his experimental brand of mechanistic science is the only legitimate approach to developmental research. Maintains that Gottlieb exaggerates developmental uncertainty, based on his own research with extreme environmental manipulations.…

Argues that a truly developmental behavior genetics will have to go beyond the traditional quantitative approach of population genetics in order to produce developmental explanatory content about differences and similarities in developmental outcomes. (MDM)

This article describes four single-subject research designs comparing two or more interventions with young disabled children--the multitreatment design, alternating treatments design, adapted alternating treatments design, and parallel treatments design. Problems in using these designs include multitreatment interference, nonreversibility of some…

Comments on some methodological limitations of the research base of "The Bell Curve": blind use of the normal distribution (bell curve); avoidance of nonnormal statistical distributions, which are more appropriate for some social and economic characteristics; copious use of percentiles and quintiles, inappropriate with nonnormal…

Two ways of studying lives in context through time are analysis of longitudinal data and secondary data analysis of long-term studies intended to answer questions not originally posed. The opportunities for, and limitations of, these types of analysis; their relevance to policy; and their applicability to interdisciplinary research are considered.…

A study examined effect-size reporting in 23 quantitative articles reported in "Exceptional Children". Findings reveal that effect sizes are rarely being reported, although exemplary reporting practices were also noted. Reasons why encouragement by the American Psychological Association to report effect size has been ineffective are…

Comments on several quantitative approaches to semantic knowledge representations (the focus of this special issue). Points out some of the ways in which Latent Semantic Analysis and Hyperspace Analog to Language fall short of being plausible theories about psychological reality. Examines in-principle failures and wrong-kind failures that arise in…

This chapter serves as a guide for quantitative researchers who seek to approach their research questions critically.
