In this article, we study the Monty Hall three doors problem. A fully general solution and several new approaches are presented, including a Bayesian analysis.

The impending retirements of many community college leaders creates a need to better understand who the chief academic officers (CAOs) are and the paths they followed to become CAOs. Nonetheless, researchers have paid relatively little attention to this important leadership position. To address this gap in the literature, the authors undertook a…

Research on the lack of civic and political engagement on the part of today's youth has relied on traditional, often quantitative, measures of political knowledge that may miss important elements of the process. Using an ethnographic approach with a group of inner-city high school students, our study reveals a richer construction of students'…

In October/November 2009, the Forum on Education Abroad conducted its third State of the Field Survey. This survey provides an annual or biannual assessment of key education abroad issues and topics of interest to Forum members and the field of education abroad at large. Previous State of the Field surveys were conducted in 2006 and 2008. The 2009…

Bayesian techniques were developed for approximating the joint and marginal distributions of universe scores in single-facit-mixed-model designs with unknown covariance structure. Empirical results indicate that when compared with Cronbach's estimates, marginal means obtained through this procedure are substantially better predictors of subsequent…

Presents a review of fundamental concepts and applications used to address the Behrens-Fisher problem (W. Behrens, 1929 and R. Fisher, 1935), a problem in testing the difference between two population means, through fiducial, Bayesian, and frequentist approaches. (Contains 86 references.) (SLD)

Gibbs sampling was applied to obtain Bayes inferences in the case of unbalanced multilevel data when the homogeneity of variance assumption fails and when interest focuses on inferences for some or all of the groups' variances. This approach is compared to a more standard analysis based on restricted maximum-likelihood statistics. (SLD)

Studied the order-statistics models, extending the usual normal order-statistics model into one in which the underlying random variables followed a multivariate normal distribution. Used a Bayesian approach and the Gibbs sampling technique. Applied the proposed method to analyze presidential election data from the American Psychological…

Discusses , in the context of confirmatory latent class analysis, model selection using Bayes factors and (pseudo) likelihood ratio statistics. Uses a small simulation study to show that in this context, Bayes factors and the pseudo likelihood ratio statistics have the best properties. (SLD)

Individual differences in development or growth are typically handled under conventional analytical approaches by blocking on the variables thought to contribute to variation, such as sex or age. But such approaches fail when the differences are attributable to latent characteristics (i.e., variables not directly observable beforehand) within the…

In current psychological research, the analysis of data from computer-based assessments or experiments is often confined to accuracy scores. Response times, although being an important source of additional information, are either neglected or analyzed separately. In this article, a new model is developed that allows the simultaneous analysis of…

A scheme is described for locally Bayesian parameter updating in models structured as successions of component functions. The essential idea is to back-propagate the target data to interior modules, such that an interior component's target is the input to the next component that maximizes the probability of the next component's target. Each layer…

The "Facilities Performance Indicators Survey" ("FPI") supersedes and builds upon the two major surveys APPA conducted in the past: the Comparative Costs and Staffing (CCAS) survey and the Strategic Assessment Model (SAM). The "FPI" covers all the materials collected in CCAS and SAM, along with some select new data points and improved survey…

This study examines how high school students were affected by having an openly gay teacher and compares its results to a previous study (Rofes, 2000). The author's lesbian, gay, or bisexual students experienced a sense of relief that they could finally feel comfortable about themselves, as well as feeling happy that others in the school were…

This study examined the accuracy of a curriculum-based assessment for use during the eligibility process for Individuals with Disabilities Education Improvement Act (IDEA) services. The study extended a previous investigation in which performance scores of children without disabilities on the Assessment, Evaluation, and Programming System (AEPS)…
