Pre-written, supporting conversational programs written in BASIC are available for use in introductory statistics courses designed for college undergraduates and high school seniors. (MM)

This study with 45 institutionalized individuals with mental retardation and self injurious behavior (SIB) calculated conditional probability using sequential analysis techniques. It found that successive episodes of self-injury were sequentially dependent and this association was not related to frequency or rate of occurrence. The best predictor…

The seven articles in this edition show that cost-benefit analysis is emerging from the confusion of the 1980s and is probably going to become the central tool of program evaluation in the future. The modern approach involves incorporating probability distributions into the cost-benefit analysis. None of the articles are specifically…

Examples used to illustrate Simpson's paradox for secondary students include probabilities, university admissions, batting averages, student-faculty ratios, and average and expected class sizes. Each result is explained. (DC)

Simple experiences with probability can extend third graders' understanding of the need for fractions. Three activities are given which build on language-arts experiences and incorporate concepts in multiplication, graphs, and fractions. (MNS)

Discusses the probability of seeing a tire explode or disintegrate while traveling down the highway. Suggests that a person observing 10 hours a day would see a failure on the average of once every 300 years. (MVL)

Presents mathematics activities for grades three through six that focus on concepts of probability and fairness. Includes reproducible student worksheets. (MKR)

Presents activities that center on the excitement of going back to school by collecting and analyzing data and exploring probabilities. Contains reproducible student worksheets. (MKR)

Discusses ways to simulate a probability problem of interest to middle school students in which students calculate the average number of packets of trading cards purchased to obtain a complete set of cards. Simulations utilize a spinner, a table of random numbers, and a computer. Includes the BASIC program utilized in the simulation. (MDH)

Explores applications of the Fibonacci series in the areas of probability, geometry, measurement, architecture, matrix algebra, and nature. (MDH)

Included in this probability board game are the requirements, the rules, the board, and 44 sample questions. This game can be used as a probability unit review for practice on basic skills and algorithms, such as computing compound probability and using Pascal's triangle to solve binomial probability problems. (JJK)

An activity in a college statistics class had students go to a field of grass and clover and use a variety of estimation, probability, sampling, distribution, and calculation techniques for determining the number of flowers in the field. The activity focused on the discovery process, encouraged abstract reasoning, and was pleasurable. (MSE)

The discrete mathematics topics of trees and computational complexity are implemented in a simple reliability program which illustrates the process advantages of the PASCAL programing language. The discussion focuses on the impact that reliability research can provide in assessment of the risks found in complex technological ventures. (Author/JJK)

A variety of suggestions for making the mathematics curriculum more meaningful and interesting to students are described. Activities that incorporate real-world situations are provided for verbal items, common and decimal fractions, estimations and rounding off numbers, large and small numbers, geometry, probability, and statistics. (KR)

Reports information retrieval experiments comparing the performance of a probabilistic retrieval model that incorporates interdocument links with the simpler spreading activation strategy. Results indicated that the overall improvement obtained by including hypertext links in the retrieval model was low. (30 references) (EA)
