This paper reviews the concept of experimentwise Type I error. While "testwise" alpha refers to the probability of making a Type I error for a single hypothesis test, "experimentwise" error refers to the probability of having made a Type I error anywhere within the study. Experimentwise error concerns are the basis for two…

Criteria for assessing variable performance in multivariate analysis of variance (MANOVA) are considered, examining criteria suggested by Huberty and Wisenbaker (1992), the contribution to linear discriminant function scores and the contribution to grouping variable effects. It is proposed that the two criteria be amalgamated as the contribution…

Proposes a comprehensive approach, generalized constrained multiple correspondence analysis, for imposing both row and column constraints on multivariate discrete data. Each set of discrete data is decomposed into several submatrices and then multiple correspondence analysis is applied to explore relationships among the decomposed submatrices.…

Average reliability of the coefficient is suggested as a multivariate extension of the classical reliability coefficient. It is shown that this coefficient is identical to the mean redundancy of the observed variables conditional on the true variables. (Author/SLD)

A nonparametric class of intervariable association indeces is presented that follows the logic of point symmetry adjustment of the Pearsonian phi coefficient. This approach is extended to multipoint scales. These indeces may be attractive alternatives to the Pearson correlation coefficient for multivariate analyses. (SLD)

Proposes a method for performing survival analysis with latent variables with dual aims of scoring subjects with respect to a psychological variable of interest and distinguishing the varying extents to which items are capable of measuring the construct. Illustrates this discrete proportional hazards model. (SLD)

Proposes a generalization of Cohen's kappa coefficient (J. Cohen, 1960) to address the problem of accounting for overall chance-corrected interobserver agreement among the multivariate ratings of several judges. The statistic's metric is conventional and in the univariate case it is equivalent to existing extensions of the kappa coefficient to…

K-means cluster analysis is known for its tendency to produce spherical and equally sized clusters. To assess the magnitude of these effects, a simulation study was conducted, in which populations were created with varying departures from sphericity and group sizes. An analysis of the recovery of clusters in the samples taken from these…

This study describes discourse patterns produced by 46 Alzheimer disease (AD) patients and 53 normal elderly subjects in two picture-supported narratives. Nine measures derived from a cognitive model of discourse processing were obtained and submitted to cluster analysis. Results indicate that discourse patterns elicited from both stimuli were…

The paper reports on a study among primary-school students of the process of deriving word meaning from written context in a first language. A sequential analysis of think-aloud protocols revealed that the students inferred one or more meanings, checked their inferences and then rejected or accepted them. These activities were performed in a…

An extension of multiple correspondence analysis is proposed that takes into account cluster-level heterogeneity in respondents' preferences/choices. The method involves combining multiple correspondence analysis and k-means in a unified framework. The former is used for uncovering a low-dimensional space of multivariate categorical variables…

This paper demonstrates a new application of cluster analysis to segment business school students according to their degree of satisfaction with various aspects of the academic program. The resulting clusters provide additional insight into drivers of student satisfaction that are not evident from analysis of the responses of the student body as a…

The No Child Left Behind Act (NCLB, 2001) requires that all schools demonstrate that their students meet or exceed expectations on various measures of academic performance. This means that stakeholders at every level of the school system, including school counselors, must demonstrate how their efforts lead to greater student achievement (Bemak,…

The assertion that there are a limited set of generalizable good educational practices (Chickering & Gamson, 1987) with a common model of preferred active student engagement in learning (Kuh, 2001) is appealing to those responsible for simply stated institutional outcomes and to the faculty who teach in fields that espouse the same practices…

Two groups of teacher candidates, enrolled either in a field-based or campus-based program, were measured before and after their first semester of teacher education courses and again at the end of their student teaching semester. The two groups were compared regarding their knowledge of multicultural education issues, dispositions towards diverse…
