This paper is concerned with the construction of effect size standard errors in situations where the effect sizes are independent but the data have likely been sampled from non-normal distributions, and possibly for different studies, from different families of non-normal distributions. Asymptotic distribution-free estimators are provided for two…

The No Child Left Behind Act (NCLBA) requires that states improve academic performance so that all students reach proficiency in reading and math by 2014 and that achievement gaps close among student groups. States set annual proficiency targets using an approach known as a status model, which calculates test scores 1 year at a time. Some states…

The National Household Education Survey (NHES) is a data collection system of the National Center for Education Statistics that concentrates on aspects of education that can best be addressed through contacts with households rather than institutions. The NHES is a telephone survey of the noninstitutionalized civilian population of the United…

This report describes the methods and procedures used for the 2000 National Postsecondary Student Aid Study (NPSAS:2000). NPSAS:2000 included notable changes from previous NPSAS surveys (conducted in 1987, 1990, 1993, and 1996) in its sample design and collection of data. For example, this study is the first to restrict institutional sampling to…

This paper focuses on methodological issues in applying equipercentile equating methods to pairs of tests that do not meet the assumptions of equating. This situation is referred to as a concordance situation, as opposed to an equating situation, and the end result is a concordance table that gives "comparable" scores between the tests.…

This technical report documents the methodology of the National Education Longitudinal Study of 1988 (NELS:88) base year survey of eighth graders through the 1992 second followup survey of high school students and dropouts. Chapter 1 begins with an overview and history of the NELS:88 and its database, Chapter 2 contains a description of the data…

The Private School Universe Survey (PSS) is a mail survey conducted by the Bureau of the Census under the sponsorship of the National Center for Education Statistics. The survey is designed to provide data relating to all private schools in the United States, but the private schools' list frame remains incomplete despite the best efforts to…

The adequacy of equipercentile, linear, one-parameter (Rasch), and three-parameter logistic item-response theory procedures for equating 12 forms of five tests of general educational development were compared. Results indicated the equating method adequacy depends on a variety of factors such as test characteristics, equating design, and sample…

Methods of using simplified time series analysis (STSA) in evaluating clinical programs are discussed. STSA assists in addressing problems of attrition/augmentation of subjects in programs with changing populations. Combining individually calculated "C" statistics in a simple aggregate analysis of restraint usage by nursing home staff…

Bayesian and empirical Bayes approaches to shrinkage estimation of regression coefficients and uses of these in prediction (i.e., analyzing intelligence test data of children with learning problems) are investigated. The two methods are consistently better at predicting response variables than are either least squares or least absolute deviations.…

Describes the of attribute sampling to estimate characteristics of library collections and operations. The nature of statistical sampling and making a statistical inference are covered, and examples from library situations are given. Tables of determination of sample size and evaluation of results are included. (Contains six references.) (EAM)

A method is presented to use school-level attributes in sample description and random assignment of schools to conditions in drug prevention programs. Utility of archival data was examined using multivariate canonical techniques, and it was found that a small set of data could predict observed variations in drug use. (SLD)

Documents the methodology of the second follow-up interview of the Baccalaureate and Beyond Longitudinal Study, describing sample design, instruction development and data collection, response rates, efficacy of the survey instrument, and weights and design effects. (Author/SLD)

This study inventoried the types of developmental and negative experiences that youth encounter in different categories of extracurricular and community-based organized activities. A representative sample of 2,280 11th graders from 19 diverse high schools responded to a computer-administered protocol. Youth in faith-based activities reported…

The immediate and long-term effects of a Parent Child Interaction Therapy (PCIT) derived program offered at a Kaiser Permanente facility were evaluated. There were 73 participants in the initial sample and 23 in the 5-6 year follow-up sample. Child behaviors improved significantly immediately following treatment and some improvements were…
