Suggestions are made on effective presentations by evaluators of research studies to audiences who are not statisticians. Examples of effective presentation methods are given: analogies in presenting statistics; graphs or pictorial presentations; summaries to highlight findings; concise reports based on a television newscast style; and judicial…

Condensed norms are presented for the most recent American Chemical Society examinations. These are the polymer chemistry form 1978, organic chemistry form 1978, physical chemistry form 1976 I, brief qualitative analysis form 1977B, and brief organic chemistry form 1977B examinations. (BB)

Class data pools on abused and neglected children and their families are found desirable for program planning, but identification by name is of questionable value and possibly a dangerous invasion of civil liberties. (MS)

History of librarians--definitions, qualifications, numbers, current status, and statistical data. (LS)

This article describes the organization and results of the 1990 New Zealand Children's Census. This census, which preceded a National Census, provided a powerful tool for raising statistical awareness nationwide. (Author)

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)

Describes new U.S. Census system dividing counties into 11 classification groups. Defines five metropolitan and six nonmetropolitan county classifications. Briefly discusses principles of new system, which uses 1980 census figures in attempt to reflect character of development in each county. Contains three charts. (TES)

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…
