Secondary analysis of datasets can extend previous work in the field, provide a greater quantity of material, and has the advantages of speed and lower cost. More use of secondary data could improve the low esteem of educational research. (Contains 15 references.) (SK)

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…

Latinos are the youngest and fastest growing ethnic group in the United States. It is imperative that institutional leaders and decision makers have a better understanding of Latino students today in order to shape the policies and practices to serve college students in the future. Currently, disparate statistics about Latino students in higher…

Rural hospitals commonly have difficulty providing surgical services despite potential economic benefits. Purpose: The purpose of this project was to identify the key challenges…

The German version of the Strengths and Difficulties Questionnaire (SDQ) was used in a study to examine its usefulness in diagnosing socioemotional problems of deaf and hard of hearing children. The SDQ parent version was completed by 213 mothers and 213 fathers. The factor structure and reliability were tested, and the prevalence rate of…
