This is the decade of data analytics and big data, but not everyone agrees with the definition of big data. Some researchers see it as the future of data analysis, while others consider it as hype and foresee its demise in the near future. No matter how it is defined, big data for the time being is having its glory moment. The most important…

This report presents findings on crime and violence in U.S. public schools, using data from the 2015-16 School Survey on Crime and Safety (SSOCS:2016). First administered in school year 1999-2000 and repeated in school years 2003-04, 2005-06, 2007-08, 2009-10, and 2015-16, SSOCS provides information on school crime-related topics from the…

Commentaries regarding appropriate methods for researching professional development have been a frequent topic in recent issues of "Educational Researcher" as well as other venues. In this article, the authors extend this discussion by observing that randomized trials of specific professional development programs have not enhanced our…

Child Trends has been asked by the Annie E. Casey Foundation to identify key opportunities that a new Administration might pursue to improve the capacity of the federal statistical system to monitor child and youth well-being. In this paper the authors discuss a number of areas of opportunity, offering concrete steps that can be taken, generally…

Incomplete or missing data is a common problem in almost all areas of empirical research. It is well known that simple and ad hoc methods such as complete case analysis or mean imputation can lead to biased and/or inefficient estimates. The method of maximum likelihood works well; however, when the missing data mechanism is not one of missing…

A new line of research has emerged that examines the prevalence rates of mixed methods within disciplines in the social/behavioral sciences. Research presented in this article is unique in that it examines prevalence rates across multiple disciplines using an established cross-disciplinary classification scheme. Results indicate that there are…

The National Household Education Survey (NHES) is a data collection system of the National Center for Education Statistics. The NHES is a telephone survey of the noninstitutionalized civilian population using households selected using random digit dialing methods. Approximately 60,000 households are screened for each administration, and people who…

Norm-referenced tests yield information regarding a student's performance in comparison to a norm or average of performance by similar students. Norms are statistics that describe the test performance of a well-defined population. The process of constructing norms, called norming, is explored briefly in this paper. Some of the most widely reported…

Comparisons were made between self-reports from 382 men and 51 women who had experienced sexual coercion while incarcerated. Victim data were obtained from a sample of 1,788 male inmates and 263 female inmates who responded to an anonymous written survey distributed in 10 midwestern prisons. Men reported that their perpetrators in worst-case…

This technical report provides an updated assessment of the problem of optimizing the periodicity of the Schools and Staffing Survey (SASS). Making use of data from three rounds of SASS data collection (for school years 1987-88, 1990-91, and 1993-94), the report extends and updates the preliminary findings and interim assessments that were…

Several statistical rational and empirical procedures are presented for dealing with the problems of non-response or low return rates in surveys, namely mail surveys. Advantages and shortcomings of these procedures in educational research are discussed. (SLD)

This document provides a summary and evaluation of the methodological procedures and results of the full-scale implementation of the Beginning Postsecondary Student Longitudinal Study Second Follow-up, 1990-94 (BPS:90/94). The study was conducted for the National Center for Education Statistics by Research Triangle Institute with the assistance of…

Possible bias due to sampling problems or low response rates has been a troubling "nuisance" variable in empirical research since seminal and classical studies were done on these problems at the beginning of this century. Recent research suggests that: (1) earlier views of the alleged bias problem were misleading; (2) under a variety of fairly…

Although the same general research principles that guide other investigations should apply to research with the Rorschach Inkblot Method, the nature of the Rorschach as a relatively unstructured measure of personality functioning calls for special attention to selection of research participants, choice of variables, and data collection and…

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…
