Illustrates a simple nonparametric alternative that can be used to test a hypothesis that two proximity matrices on the same set of variables or objects reflect a similar pattern of high and low entries. (RC)

Investigates the Tukey statistic for the empirical probability of a Type II error under numerous parametric specifications defined by Cohen (1969) as being representative of behavioral research data. For unequal numbers of observations per treatment group and for unequal population variancies, the Tukey test was simulated when sampling from a…

Monte Carlo procedures are used to develop stress distributions using Kruskal's second stress formula. These distributions can be used in multidimensional scaling procedures to determine whether a set of data has other than random structure. (Author/JKS)

Two experiments were designed to provide an empirical test of an attribution model of psychopathology and to extend it to the clinical problem of social anxiety. Specifically, the research examines the relation between social anxiety and attributions of success and failure in heterosexual interactions. (Author/RK)

Employing the Minnesota Satisfaction Questionnaire and the Leader Behavior Description Questionnaire, this study investigates the relationship between the job satisfaction of Georgia school superintendents and perceived leader behavior of Georgia school board presidents. (JC)

Marascuilo's and Levin's use of the term "nesting" to describe a statistical model, and application of the Scheffe tests on restricted sets of contrasts, is opposed. Changing the model during analysis of a complex set of data is both necessary and desirable. (Author/CP)

Four testing procedures for establishing the number of non-zero population roots in canonical analysis are investigated. Results of a Monte Carlo study indicate that three well-established procedures were effective, and a new procedure designed to correct a supposed flaw in the other procedures was ineffective. (JKS)

Techniques are developed for constructing confidence regions for each of the points in a multidimensional scaling solution. Bayesian credibility regions are discussed, and a technique for displaying these regions is described. (Author/JKS)

The relationship between variables in applied and experimental research is often investigated by the use of extreme groups. Recent analytical work has provided an extreme group procedure that is more powerful than the standard correlational approach. The present article provides procedures to optimize power and thusly resources in such studies.…

A series of independent, normally distributed events may be broken into intervals on an a priori basis. Then, within interval variance may be compared to among interval variance. These might be considered short-term and long-term variances. This concept and a test for comparing variances are presented. (Author/JKS)

Two potentially useful tests for homogeneity of variance--the jackknife test and the Box test--are described and compared. Recommendations for the use of these techniques and computational examples of each are provided. (Author/JKS)

Discusses the relation between discrimination and identification performance, particularly with regard to experiments with speech and other signals used to draw a distinction between continuous and categorical perception. Offers three main arguments. (Author/RK)

Measurement error in dependent variables reduces the power of statistical tests to detect mean differences of specified magnitude. Procedures for determining power and sample size that consider the reliability of the dependent variable are discussed and illustrated. Methods for estimating reliability coefficients used in these procedures are…

The asymptotic power of the Cramer-von Mises test when parameters are estimated from the data is studied under certain local (contiguous) alternatives. Notion of (asymptotic) direction and distance from the null hypothesis of alternatives is introduced, and it is shown that there exist directions with maximum, minimum, and arbitrary intermediate…

Some objections (EJ 156 226) to an earlier article of mine (EJ 123 711) concerning the use of hypothetical moral situations in moral education are first examined. It is then argued that to characterize morality as a wholly "public" or "private" affair is mistaken, as moral decision-making must involve a combination of both…
