Two techniques for interpretation of fitted log-linear models in contingency table analysis are discussed. The use of odds ratios as opposed to direct interpretation of the fitted model is argued for. (Author/JKS)

Provides information concerning a procedure for estimating the probability of placement error on a criterion referenced multiple choice test. (TJ)

Presents an alternative derivation of the Fokker-Planck equation for the probability density of a random noise process, starting from the Langevin equation. The derivation makes use of the first two derivatives of the Dirac delta function. (Author/GA)

Emphasizes the importance of precisely defining symbols introduced in deriving relationships between experimental and/or theoretical quantities. An example of a rate constant in unimolecular reaction rate theory is given. (SA)

Discusses a reliability theoretic construct focusing on information produced to satisfy specified purposes or achieve preconceived objectives. When measures of system reliability and sensitivity analyses are performed, the result is a closer congruence between the objectives of the data producer and user requirements. (Author/MBR)

Tries to explain the attraction between unlike charged particles using electromagnetic interaction as described by the quantum field theory. (GA)

Annual records of the one-mile sun can be used to introduce a variety of statistical ideas including the scatter diagram, theoretical vs. observed values, and normal equations. (SD)

This article presents problems to challenge students over and above the standard curriculum problems assigned at a Course I level. Every additional problem in the article can be solved using only the tools provided by Course I. (AIM)

Describes a classroom problem of probability as follows: How many people do you need in a group to ensure that the probability of at least two of them having the same birthday is greater than one-half? Answer: 23. The probability principles needed are simple enough to be accessible to advanced high school students. (PVD)

Describes how three experiments suitable for upper-elementary students can be used to foster classroom discourse in which students begin to explore probability. (KHR)

Explores different types of Bingo games in which students can work on mental arithmetic, solve equations, and recognize geometric shapes. (KHR)

Process Analysis is described as a method for identifying and measuring the probability of events that could cause the failure of a program, resulting in a cause-and-effect tree structure of events. The method is illustrated through the evaluation of a pilot instructional program at an elementary school. (SLD)

Discusses a commonly held misconception that in the throwing of two dice, if a total of seven does not come up for a period of time then its appearance is imminent. Describes an experiment to disprove the misconception and includes a discussion of the theory that frames the results. (DDR)

Discussion of relevance feedback in information retrieval focuses on a proposal for the Bayesian Network Retrieval Model. Bases the proposal on the propagation of partial evidences in the Bayesian network, representing new information obtained from the user's relevance judgments to compute the posterior relevance probabilities of the documents…

Explains the critical role of probability in making sense of quantum physics and addresses the difficulties science and engineering undergraduates experience in helping students build a model of how to think about probability in physical systems. (Contains 17 references.) (Author/YDS)
