Data from the National Incidence Study (NIS) of Child Abuse and Neglect suggest no racial difference in child maltreatment, although there are more black children within the child welfare population. This study found selection bias in the NIS design caused by the exclusion of family, friends, and neighbors that resulted in differences in NIS cases…

Three methods based on the nonparametric item response theory (IRT) of R. J. Mokken for the estimation of the reliability of single dichotomous test items are discussed. Analytical and Monte Carlo studies show that one method, designated "MS," is superior because of smaller bias and smaller sampling variance. (SLD)

In post-apartheid South Africa, the tenets of inclusivity, nondiscrimination, and tolerance are actively encouraged and legislated across all sectors of society, including education. However, in examining the coming out experiences of 18 South African gay and lesbian youth (1997-2000), it became apparent that they had all experienced…

Internet job searching offers an empirical setting in which to explore the trade-off between quality and quantity of information. As both firms and workers turn to the internet for unprecedented amounts of labor market information, it is unclear whether this makes the matching process more efficient. Using longitudinal data on two samples of…

The standardized group mean difference, Cohen's "d", is among the most commonly used and intuitively appealing effect sizes for group comparisons. However, reporting this point estimate alone does not reflect the extent to which sampling error may have led to an obtained value. A confidence interval expresses the uncertainty that exists between…

Water quality experiments, especially the use of macroinvertebrates as indicators of water quality, offer an ideal context for connecting statistics and science. In the STAR program for secondary students and teachers, water quality experiments were also used as a context for teaching statistics. In this article, we trace one activity that uses…

Two psychometric models are presented for evaluating the difficulty of the distractors in multiple-choice items. They are based on the criterion of rising distractor selection ratios, which facilitates interpretation of the subject and item parameters. Statistical inferential tools are developed in a Bayesian framework: modal a posteriori…

The goal of the present investigation is to compare the factor structure of the revised NEO Personality Inventory (NEO PI-R; P. T. Costa & R. R. McCrae, 1992) in samples of respondents differentially motivated to respond in a socially desirable manner. In the French sample, the authors compared the NEO PI-R structure of job applicants…

There is not a "typical" women's group, nor are there "typical" women's issues. Every women's group is diverse, with as many viewpoints and perspectives as there are members in the group. Using the group format for women is common practice with many counselors. It is interesting that there has been little empirical research reported on women's…

This study analyzed data from the School Health Policies and Programs Study (SHPPS) 2000 to examine the relationship between school health councils and selected school health policies and programs. SHPPS 2000 collected data from faculty and staff in a nationally representative sample of schools. About two-thirds (65.7%) of US schools have school…

The Monitoring the Future (MTF) study involves an ongoing series of national surveys of American adolescents and adults that has provided the nation with a vital window into the important, but largely hidden, problem behaviors of illegal drug use, alcohol use, tobacco use, anabolic steroid use, and psychotherapeutic drug use. For more than a third…

In this paper, a data perturbation method for minimizing the possibility of disclosure of participants' identities on a survey is described in the context of the National Assessment of Educational Progress (NAEP). The method distinguishes itself from most approaches because of the presence of cognitive tasks. Hence, a data edit should have minimal…

This report serves as the survey documentation for the design and implementation of the 2003-04 Schools and Staffing Survey. Topics covered include the sample design, survey methodology, data collection procedures, data processing, response rates, imputation procedures, weighting and variance estimation, review of the quality of data, the types of…

This study was an investigation of the educational needs of tuk-tuk drivers when using English to communicate with tourists in Phranakhon Si Ayutthaya, an old capital of Thailand. The samples included 30 tuk-tuk drivers at five famous places where tourists require tuk-tuk drivers' services in Phranakhon Si Ayutthaya, for example at the train…

Background/Context: In order to develop effective strategies for retaining able and committed teachers, it is important to understand how new teachers experience their work with their colleagues. A previous qualitative study conducted by the authors and others presented a conceptual framework for understanding new teachers' experiences of the…
