Used conjoint measurement to describe how systems-oriented therapists predict the occurrence of suicide. Although the systems approach emphasizes the interaction between an individual and a system, all 10 clinicians were described by an additive model. (Author/JAC)

The interpretation of significant left-tailed analysis of variance (ANOVA) F-ratios is supported by considering the case of a fixed effects ANOVA model. The conclusions of this case are generalizable to other standard ANOVA models. (Author/PN)

A class of naive estimators of correlation was tested for robustness, accuracy, and efficiency against Pearson's r, Tukey's r, and Spearman's r. It was found that this class of estimators seems to be superior, being less affected by outliers, reasonably efficient, and frequently more easily calculated. (Author/CTM)

This review of the procedures involved in using path analysis provides guidelines for more effective future utilization of recursive path analysis in the field of family studies. (Author)

The importance of reporting explained variance in ANOVA designs is discussed. Three methods that can be used to obtain estimates of explained variance in ANOVA designs are described and applied to sixteen studies that were reported in recent NARST volumes. Recommends that researchers in science education report explained variance. (Author/DS)

The determination of a consensus ranking of products based on the rankings of each judge can be accomplished through the use of a Tukey type multiple comparison procedure. The extension to more than two groups is presented as an analysis of concordance table. (Author/CTM)

Demonstrates the advantages of a p-value as compared with a standard significance test procedure. Contains examples in the discussion of testing the mean of a normal distribution and testing a probability of proportion. (DDR)

Counters arguments of Donald N. McClosky on formalism in the social sciences and claims he fails to identify important arguments that justify the practices he criticizes. Agrees that, although exposing accepted methods to critical examination is useful, this broad attack implies the rejection of good social science as well as bad. (NL)

The mean and variance of the statistic psi-star, which is useful for measuring agreement between two raters and allows for tests of significance in the case of large samples, are considered. Results may also be applied for the "G" index of J. W. Holley and J. P. Guilford (1964). (SLD)

A critical reanalysis of Barrett, Caldwell, and Alexander's (1985) critique of dynamic criteria. Summarizes and questions Barrett, et al.'s three definitions of dynamic criteria and their conclusion that reported temporal changes in criteria could be explained by methodological artifacts. A greater focus on dynamic criteria as constructs is…

Responds to Austin, Humphreys, and Hulin's (1989) critique of Barrett, Caldwell, and Alexander, suggesting that the burden of proof still rests on the advocates of the concept of dynamic criteria, and that empirical support is lacking for the existence of dynamic criteria as a simplex. Contrary evidence from educational, organizations, and…

Two coefficients ("H" and "C") for evaluating the homogeneity or congruence of a set of ratings or scores are described. Statistical tests of the significance of these indexes are presented, along with a description of a computer program (CHOPRO) for determining values of "C" and "H" and associated…

The study examining the validity of statistical conclusions of 49 early intervention studies found that 4 percent had adequate power to detect medium intervention effects and 18 percent to detect large intervention effects. Low statistical conclusion validity has practical consequences in program evaluation and cost-effectiveness determinations.…

This commentary on EC 603 695 argues that significance testing is a necessary but insufficient condition for positivistic research, that judgment-based assessment and single-subject research are not substitutes for significance testing, and that sampling fluctuation should be considered as one of numerous epistemological concerns in any…

Considers reviews of L. Daniels's article on editorial policy regarding statistical significance testing and concludes that the controversy is not over, although the gradual movement toward requiring additional information in the reporting of statistical results is viewed as a positive trend. (SLD)
