Presents a problem that has been well received by students in undergraduate mathematical statistics courses. The problem is presented as a game in which students are asked to choose between two alternatives, as if they were betting. (ASK)

Presents an activity in which students develop a handy strategy for exploring probability as applied in the life sciences by learning to use the Punnett square, an effective tool that helps students visualize sample spaces and determine the likelihood of events. (ASK)

Observes the application of probability theory to a game between two players. Shows how basic techniques such as tree diagrams can be used to demonstrate optimum strategies, how the art of bluffing can be quantified, and how this might be applied to a game of poker. (Author/ASK)

Investigates whether state course graduation requirements affect high-school dropout decisions, using aggregate data on dropout rates, individual data from two time periods, and aggregate data on high-school completion rates over 15 years. Results strongly suggest that state-mandated minimum course requirements cause students to drop out.…

Objective: According to mandatory reporting laws for professionals, the relationship between initial recognition that a child may have been abused and the subsequent reporting of that suspected case of child abuse to the responsible agency would, at first glance, appear to be clear. However, this relationship has developed into one of the major…

We conducted functional analyses and identified reinforcers for problem behavior for three individuals with developmental disabilities. Based on results of the functional analysis, we evaluated the rate, probability, delay, and duration of reinforcement for problem and appropriate behavior during descriptive parent-child observations. Results…

The authors examine the relationship between students' locus of control and their evaluation of teaching in a traditional principles of economics course. Locus of control is a psychological construct that identifies an individual's beliefs about the degree of personal control that can be exercised over his or her environment. Students with an…

This study attempts to improve our understanding of the prevalence and determinants of violent death in rural Bangladesh. Data came from a demographic surveillance system covering a population of nearly 62,000 in 10 districts of the country. Findings reveal that drowning and homicide were the leading causes of death followed by traffic accident…

Using American Citizen Participation Survey data (Verba et al. 1995a), we perform logistic regression analyses to adjudicate between three core explanations for individual protest: biographical availability, political engagement and structural availability. We calculate estimated probabilities to weigh the relative effects of these factors on the…

Substantial gaps in achievement of groups of individuals of varying social status are well documented, but there are no conclusive explanations for them. The author integrated psychological and educational perspectives to scrutinize the effects of 4 protective factors believed to promote academic resilience of students at risk because of low…

Binary outcome data are common in research and evaluation. They are often analyzed using logistic regression, and results of these analyses are often reported in the form of odds ratios (ORs). However, ORs are not directly interpretable in the metric commonly used in policy-relevant discussions, which concerns probabilities. ORs are unfamiliar to…

The effect of person misfit to an item response theory model on a mastery/nonmastery decision was investigated. Furthermore, it was investigated whether the classification precision can be improved by identifying misfitting respondents using person-fit statistics. A simulation study was conducted to investigate the probability of a correct…

Context: Rural residents are disproportionately represented among the uninsured in the United States. Purpose: We compared nonelderly adult residents in 3 types of nonmetropolitan areas with metropolitan workers to evaluate which characteristics contribute to lack of employment-related insurance. Research Design and Analysis: Data were obtained…

The present study was designed to identify the impact of drinking problems, impulsivity, and a history of childhood physical abuse on both male-to-female (MFIPV) and female-to-male intimate partner violence (FMIPV). The data were collected in 1995 from a representative national sample of couples living in the contiguous 48 states. Using a…

In earlier work we have shown that adults, infants, and cotton-top tamarin monkeys are capable of computing the probability with which syllables occur in particular orders in rapidly presented streams of human speech, and of using these probabilities to group adjacent syllables into word-like units. We have also investigated adults' learning of…
