Attempts to distill a growing technical literature on repeated-measures analysis of variance into a few simple principles for selecting an analytic technique. Argues that researchers ought not opt for a general analysis strategy when current computer technology makes it possible to select the optimal analysis technique for a given data set. (RH)

This paper discusses the sample size problem and four factors affecting its solution: significance level, statistical power, analysis procedure, and effect size. The interrelationship between these factors is discussed and demonstrated by calculating minimal sample size requirements for a variety of research conditions. (Author)

This paper developed and illustrated a technique to analyze categorical data when subjects can appear in any number of categories for multigroup designs. Post hoc procedures to be used in conjunction with the presented statistical test are also developed. The technique is a large sample technique whose small sample properties are as yet unknown.…

The basic notion of variability is generalized from a univariate context to a multivariate context using two matrix functions, a determinant, and a trace, yielding a number of alternative multivariate indices of shared variation. Some problems in the interpretation of tests of multivariate hypotheses are reviewed. (Author/BW)

The general class of continuous growth models are described and examples representative of growth models suggested for various types of academic and/or physical growth are given. The fan spread hypothesis is discussed in relationship to natural growth models, as well as differential linear growth. (PN)

A method is developed for testing a priori multiple regression models. The method allows one to specify in advance as many unstandardized or standardized coefficients as one wants to and allows the remaining slopes to be free to vary. (Author/PN)

Reports two experiments relevant to the questioning strategies counselors use in testing their hypotheses about clients. Results supported the idea that counselors are able to take a tentative hypothesis about a client and test its accuracy against additional independent, unbiased observations of the client. (LLL)

Details of a reasonably precise normalization technique for coefficient alpha are outlined, along with methods for estimating the variance of the normalized statistic. These procedures lead to the K-sample significance test. (RC)

Are creative people highly self-actualized? Are self-actualized people highly creative? This research project attempts to understand and define these two concepts more clearly, and to answer the above questions. (Author/RK)

Tries to overcome deficiencies in devising and testing indices of syntax by synthesizing the insights of both American and English research and testing the syntactic aspect of Bernstein's elaborated and restricted codes with a large, systematically classified sample of Australian schoolchildren. (Author/RK)

Introversion and extraversion, anxiety, and the fourteen personality source traits of the High School Personality Questionnaire were tested as discriminants for categorizing children as expressing aversion to physical punishment or detention. (Editor)

Eidetic imagery involves the ability to examine a visual stimulus briefly and later project onto a neutral surface an image that represents an exact duplication of the original. This study uses the differential frequency of eidetic imagery ability between children and adults as a basis for testing the validity of hypnotic age regression.…

Tested the hypothesis that cognitively complex judges will be more attracted to similar others than to dissimilar others, while cognitively simple judges will not be differentially attracted to similar and dissimilar others. (Author/RK)

Many program evaluations involve some type of statistical testing to verify that the program has succeeded in accomplishing initially established goals. In many cases, this takes the form of null hypothesis significance testing (NHST) with t-tests, analysis of variance, or some form of the general linear model. This paper contends that, at least…
