The aim of this study was to investigate forces that affect the timing of women's exit from violent relationships with men. Abused women were recruited from posters in the community and battered women's shelters, interviewed, and followed up for 10 years. Data for this study are based on 100 women and were analyzed using event history analysis.…

Background: Publication is the primary means of contributing to and establishing credibility within the scientific community. Some researchers have reported an increase in the average number of authors per manuscript for some scholarly journals in the past two decades. Whereas author proliferation may be warranted in some cases, other reasons for…

This handbook is an effort to establish current and consistent terms, definitions, and classification codes to maintain, collect, report, and exchange comparable information about students. It is a reference guide to those concerned with the collection of student data. Definitions reflect a consensus about best practice in the field of education…

The major emphasis of the National Longitudinal Study of the High School Class of 1972 (NLS) has been directed toward individuals in the 1972 high school graduating class. Consequently, sampling parameters were established to ensure student representation, and the bulk of data collected were individual-level data. School-level data exist on a…

The present study examined three different methods of data collection in which subjects judged proximity between object pairs. One method required subjects to partition objects into homogeneous subsets; the second entailed rating object pairs on a similarity-dissimilarity continuum; and the third involved comparing inter-object proximities to a…

Levin's (1975) sample-size determination procedure for completely randomized analysis of variance designs is extended to designs in which antecedent or blocking variables information is considered. In particular, a researcher's choice of designs is framed in terms of determining the respective sample sizes necessary to detect specified contrasts…

Several questions are raised concerning how data is collected and interpreted to generate the National Inventory of Library Needs. The author urges NCLIS to confront some basic issues which have been raised by the document, including data collection techniques and the professional backgrounds of the individuals involved in the study.

This article summarizes the accomplishments of the Bureau of Labor Statistics in implementing several of the Levitan Commission's recommendations to improve labor data and in conducting activities preparatory to the adoption of others. Examines changes in the Current Population Survey program, Current Employment Statistics surveys, and use of the…

This paper presents a procedure called multiple matrix sampling which simplifies data collection for drug incidence surveys. Advantages for the use of multiple matrix sampling with drug surveys are discussed and a practical example is outlined presenting the guidelines for a sampling plan. (Author)

This handbook establishes current and consistent terms, definitions, and classification codes to maintain, collect, report, and exchange comparable information about students. The handbook is useful to public and private agencies and educational institutions, researchers, policy makers, and members of the public interested in student data. The…

Before schools can tackle the student dropout problem, they need to distinguish school leavers from completers. A year-long pilot project in 31 states will record all students who drop out and their reasons for leaving, using a statistical reporting model developed by the Council of Chief State School Officers. Recommendations and participant…

Describes a current research study which is attempting to identify autism susceptibility loci by a systematic screening of the whole human genome by using multiplex families. It reviews the resources and methods used in the study including extensive collection of family data, semiautomated genotyping technology, and specialized statistical…

This manual has been produced to familiarize data users with the procedures followed for data collection and processing for the base year through second follow-up of the Education Longitudinal Study of 2002 (ELS:2002). It also provides the necessary documentation for use of the data files, as they appear on the ELS:2002 base-year to second…

In this article, the authors present a laboratory exercise in data collection and statistical analysis in biological space using clustered stomates on leaves of "Begonia" plants. The exercise can be done in middle school classes by students making their own slides and seeing imprints of cells, or at the high school level through collecting data of…

This book is a guide to categorizing, measuring, testing, and assessing aspects of language, and is intended for language teachers, speech therapists and other language-related practitioners, and researchers, in conjunction with other resources on research methods and statistics. The first part is a discussion of basic terminology and the varied…
