Proposes a plotting position formula for the Pearson type III distribution in the analysis of historical flood information. Presents results of a numerical example using actual flood data to confirm the appropriateness of the plotting formula. (24 references) (MDH)

Describes a tool that allows people to browse several characteristics of federal statistical data contained in 200 Web sites before committing to any specific site. Presents the design process used and results from usability testing for the Relation Browser tool and makes recommendations for comparable applications. (Contains 11 references.)…

Presents a statistical record of the progress of African Americans in U.S. institutions of higher education. Topics include the black-white higher education equality index; statistics that measure the state of racial inequality; the still-missing statistics on blacks in higher education; and reasons for hope regarding African Americans in higher…

In the last two decades, the United States has been in the throes of rapid economic change brought by new technologies and the globalization of the economy. One of the best ways to study the effects of change on the U.S. population is through the abundant information available on the website of the United States Bureau of the Census. In addition…

The purpose of this study was to assess the accuracy of three recommended anthropometric equations for women and then develop an updated prediction equation using dual energy x-ray absorptiometry (DXA). The percentage of body fat (%BF) by anthropometry was significantly correlated (r = .896-. 929; p [is less than] .01) with DXA, but each equation…

Philip Kendall's (1997) editorial encouraged authors in the Journal of Consulting and Clinical Psychology (JCCP) to report effect sizes and clinical significance. The present authors assessed the influence of that editorial--and other American Psychological Association initiatives to improve statistical practices--by examining 239 JCCP articles…

Through Monte Carlo simulation, small sample methods for evaluating overall data-model fit in structural equation modeling were explored. Type I error behavior and power were examined using maximum likelihood (ML), Satorra-Bentler scaled and adjusted (SB; Satorra & Bentler, 1988, 1994), residual-based (Browne, 1984), and asymptotically…

In order to learn the concept of statistical techniques one needs to run real experiments that generate reliable data. In practice, the data from some well-defined process or system is very costly and time consuming. It is difficult to run real experiments during the teaching period in the university. To overcome these difficulties, statisticians…

The comparability and quality of UNESCO's international education statistics have been questioned since the end of the 1980s, when other international agencies started producing their own indicators on education. This evolution coincides with the new strategic role given to education in national and international economic programmes, and marks the…

Less than optimum strategies for missing values can produce biased estimates, distorted statistical power, and invalid conclusions. After reviewing traditional approaches (listwise, pairwise, and mean substitution), selected alternatives are covered including single imputation, multiple imputation, and full information maximum likelihood…

Written comments on student evaluations often seem idiosyncratic, lacking the power of numerical statistical data. These statements, however, may sometimes reveal intellectual challenges common to novice learners in our disciplines. Instructors can use these insights as part of a scholarly approach to teaching, making meaningful adjustments to…

When the American Council of Learned Societies held its annual meeting in Montreal last week, topics such as open access, scholarly publishing, and "The Global Academy and the Geography of Ideas" figured on the agenda. This article discusses the first item of business at the meeting: the debut of the Humanities Indicators project, with a first set…

This study set out to identify the kinds of achievement orientations that adolescents show, and to examine the kinds of antecedents and consequences the use of a particular orientation has. The participants were 734 Swedish adolescents (335 boys and 399 girls) who filled in questionnaires measuring their achievement beliefs and behaviors,…

The risk of investment in schooling has largely been ignored. We mimic the investment decision facing a student and simulate risky earnings profiles in alternative options, with parameters taken from the very limited evidence. The distribution of rates of return appears positively skewed. Our best estimate of "ex ante" risk in university education…

The Monitoring the Future (MTF) study is 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 of a…
