A quick review of introductory textbooks reveals that while gerontology authors and instructors introduce some aspect of demography and epidemiology data, there is limited focus on age adjustment or other important epidemiology rates. The goal of this paper is to reintroduce a variety of basic epidemiology strategies such as incidence, prevalence,…

Selecting a statistical framework for a behavioral study has profoundly different results than does a linguistically framed research strategy. The linguistic strategy overcomes many limitations inherent in statistical strategies and offers more meaningful results. Inferential statistical studies often discuss how the findings "explain" the results…

This study evaluated a "substantively driven" method for scoring NAEP writing assessments automatically. The study used variations of an existing commercial program, e-rater[R], to compare the performance of three approaches to automated essay scoring: a "brute-empirical" approach in which variables are selected and weighted solely according to…

This 120-item selective annotated bibliography provides comprehensive, but not exhaustive, coverage of the publications of the U.S. Government Printing Office containing statistics on education for the period 1982 through 1991. Entries are arranged alphabetically by title and include the date published, the Superintendent of Documents…

A limitation of the principal components method is its scale dependence. This note shows that the method is scale invariant if the normalization is modified in an obvious way. Then the effect of a change in units is as transparent as in linear regression, and principal components can be used without apology. Most researchers who use multivariate…

Rasch between and total weighted and unweighted fit statistics were compared using varying test lengths and sample sizes. Two test lengths (20 and 50 items) and three sample sizes (150, 500, and 1,000 were crossed. Each of the six combinations were replicated 100 times. In addition, power comparisons were made. Results indicated that there were no…

A population data set was randomly generated from which a random sample was drawn. This sample was randomly divided into two data sets, one of which was used to generate parameter estimates, which were then used in the second data set for cross-validation purposes. The best variable subset models were compared between the two data sets on the…

The National Longitudinal Surveys (NLS), sponsored by the Bureau of Labor Statistics, U.S. Department of Labor, are a set of surveys each of which has gathered information at multiple points in time on the labor market experiences of five groups of men and women since the mid-1960s. Each group of at least 5,000 persons was selected to be…

Working from a common data base and hypothesized model, this paper demonstrates and compares the EQS and LISREL computer program strategies in the analysis of a second-order factor model. Program similarities and differences are noted with respect to: (1) preliminary analyses of the data; (2) treatment of data that are not multivariately normal;…

In January of 1987, a planning conference was convened by the Center for Education Statistics as part of an effort to study the feasibility of various approaches to the nationwide assessment of children's readiness for instruction in kindergarten and first grade. This report provides, in an appendix, the texts of the four commissioned papers…

This report offers a review of the Chicago Public Schools' official policy on promotion and retention, a discussion of research on the issue of retention, and an analysis of June, 1989 retention rates in Chicago. The first section covers retention and promotion policies in Chicago and other cities and research on the effects of retention and…

Focused on the development of definitions and guidelines for management statistics, this Systems and Procedures Exchange Center (SPEC) kit is based on the responses of 91 academic members of the Association of Research Libraries (ARL) to a survey investigating their internal uses of statistics, external statistics reporting, and tools for…

Monte Carlo methods were employed to assess the relative power of the paired samples t test and Wilcoxon's signed-ranks test under ten population shapes. Results of the study indicated that: (1) each of the two statistics was more powerful than the other in given situations; (2) the power advantages of the t test under normal theory were small;…

Over 300 resources on methods in cultural anthropology are listed under the following headings: archaeological methods; visual methods, tape recordings, and technical aids; cognitive anthropology and emic methods; community studies and complex societies; cross-cultural and hologeistic methods; ethnohistory; field work techniques and participant…

The progress of modern mental test theory depends very much on the techniques of maximum likelihood estimation, and many popular applications make use of likelihoods induced by logistic item response models. While, in reality, item responses are nonreplicate within a single examinee and the logistic models are only ideal, practitioners make…
