Large sample chi-square tests of the significance of the difference between two correlated kappas, weighted or unweighted, are derived. Cases are presented with one judge in common between the two kappas and no judge in common. An illustrative calculation is included. (Author/SLD)

Because it is sensitive to variability and permits partitioning of a distribution into the tails and center, the Hedges and Friedman Index can be used to investigate gender differences in each partition. It should yield greater insight into the nature of between-gender differences, as its application to Feingold's 1992 data illustrates. (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…

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…

Investigates two aspects of research analyses in quantitative research studies reported in the 1996 issues of "Journal of Counseling & Development" (JCD). Acceptable methodological practice regarding significance testing and evaluation of score reliability has evolved considerably. Contemporary thinking on these issues is described; practice as…

Outlines concerns that must be addressed by those who advocate replacing statistical hypothesis-testing with alternative data-analysis strategies. Suggests that commonly recommended alternatives are not perfect and that various hypothesis-testing modifications can be implemented to make the process and its conclusions more credible. Hypothesis…

Describes the MINISIZE 2 computer program, which permits the user to determine the effect size and the minimum sample size needed so that results of a given analysis will be statistically significant. Explains the program's operation and provides examples. (SLD)

In teaching research methods, introducing effect size, then power, then statistical significance will improve understanding of Type I and Type II errors. Students will develop a better grasp of decision-making processes involved in hypothesis testing, which nurses need in an environment stressing evidence-based practice. (SK)

Review states that the book gives an examination of the null-hypothesis significance test procedure as an integral component of data analysis of quantitative research studies in the social sciences. It is designed for the nonmathematics student who will be doing empirical studies involving the testing of substantive hypotheses. (SLD)

States that a method for estimating gender wage gaps by industry yields estimates that vary according to arbitrary choice of omitted reference groups. Suggests alternative methods not susceptible to this problem that can be applied to other contexts, such as racial, union/nonunion, and immigrant/native wage differences. (SK)

Suggest that the call for more pointed graduate education and more affirmative journal policies on replication-extension made by R. Hubbard and P. Ryan is useful, although inadequate and probably pointless. Statistical significance testing appears to be here to stay despite the charge that it is of "marginal scientific value." (SLD)

Surveyed AERA members regarding their perceptions of: statistical issues and statistical significance testing; the general linear model; stepwise methods; score reliability; type I and II errors; sample size; statistical probabilities as exclusive measures of effect size; p values as direct measures of result value; and p values evaluating…

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…

The intent of this study is to learn about principal intern perceptions of their grasp of the identified state principal standards for Colorado. A non-experimental comparative approach was used for this inquiry. Interns were trained to use an online journaling process called Journey Mapping. On a six point scale they rated themselves on their…

Purpose: The purpose of this paper is to evaluate the level of ICT (information and communication technologies) integration and usage in teachers, curricula in Iranian schools. Design/methodology/approach: The data for the study were gathered through a questionnaire administered to 160 respondents who were school teachers. In total, 154…
