This article explores the potential of Bayesian inference as a theoretical framework for describing how people evaluate hypotheses. First, it identifies a set of logically possible forms of non-Bayesian behavior. Second, it reviews existing research in a variety of areas to see whether these possibilities are ever realized. (Author/BW)

The present article reviews the procedures that have been developed for measuring the reliability of human observers' judgments when making direct observations of behavior. These include the percentage of agreement, Cohen's Kappa, phi, and univariate and multivariate agreement measures that are based on quasi-equiprobability and quasi-independence…

Writing short computer programs can help students to develop an understanding of random processes in probability. Three sample programs are included. (MNS)

Techniques that students can use to make predictions about performances in the Olympics include point estimation. This is used to estimate a single value using a set of data. A worksheet for students is included. (MNS)

The problem of determining which of several populations has the largest mean is considered. The procedure described by Dudewicz and Dalal is extended to the case of unequal sample sizes. (JKS)

Activities are described for a probability unit in which the Markov process is studied and applied to the weather. (DT)

The benefits of using computer simulations in teaching elementary probability topics are discussed. Sample probability problems suitable for simulation are suggested. (DT)

A variation of the classical birthday problem is considered. A BASIC program is included in the article. (DT)

A Bingo card is analyzed to determine numbers favored to win. (DT)

A major challenge to state and jurisdictional policymakers in implementing the Early Intervention Program for Infants and Toddlers with Disabilities, Part C under the Individuals with Disabilities Education Act (IDEA), is determining definitions of developmental delay and criteria of eligibility for services to young children, birth through 2…

Probability and statistics may be the horror of many college students, but if these subjects are trimmed to include only the essential symbols, they are easily within the grasp of interested middle school or even elementary school students. This book can serve as an introduction for any beginner, from gifted students who would like to broaden…

The use of matrix multiplication in the theory of Markov chains is demonstrated without directly discussing any probability theory. The technique that is developed is applied to ratio and mixture problems that are in changing states. (JP)
