A case for teaching statistics and probability in the secondary school curriculum is given. A description of and suggestions for teaching the distribution of the mean are the main points of the article. (FL)

Discusses the quantum theory of measurement and von Neumann's catastrophe of infinite regression." Examines three ways of escapint the von Neumann catastrophe, and suggests that the solution to the dilemma of inteterminism is a universe in which all possible outcomes of an experiment actually occur. Bibliography. (LC)

Included are eleven short articles on various aspects of mathematics. (FL)

Discusses the empirical importance of Shannon's Information Theory and its impact on information science, and investigates the principle of least effort as a means of broadening the empirical foundation of Information Theory. Listed are 14 sources. (Author/RBF)

A formal framework is presented for determining which of the distractors of multiple-choice test items has a small probability of being chosen by a typical examinee. The framework is based on a procedure similar to an indifference zone formulation of a ranking and election problem. (Author/BW)

The use of a quasi-equiprobability model in the measurement of observer agreement involving dichotomous coding categories is described. A measure of agreement is presented which gives the probability of agreement under the assumption that observation pairs reflecting disagreement will be equally probable. (Author/JKS)

Describes success-breeds-success phenomenon by single and multiple-urn models, and shows that these models lead to a negative binomial distribution for the total number of successes and to a Zipf-Mandelbrot law for the number of sources contributing a specified number of successes. Ten references are cited. (FM)

Discusses a 1976 survey of Comprehensive Employment and Training Act participants and factors affecting the success or failure of employment programs. (JOW)
