Reliability Analysis for the Internationally Administered 2002 Series GED (General Educational Development) Tests Reliability refers to the consistency, or stability, of test scores when the authors administer the measurement procedure repeatedly to groups of examinees (American Educational Research Association [AERA], American Psychological…

Secondary data analysis as a methodological approach is not without its critics. Indeed, three main objections to the use of secondary data analysis in social research stand out: first that because of the socially constructed nature of social data, the act of reducing it to a simple numeric form cannot fully encapsulate its complexity. Secondly,…

The hierarchical latent regression model (HLRM) is a flexible framework for estimating group-level proficiency while taking into account the complex sample designs often found in large-scale educational surveys. A complex assessment design in which information is collected at different levels (such as student, school, and district), the model also…

While the National Center for Education Statistics (NCES) has conducted surveys of attrition and mobility among school teachers for two decades, little was known about similar movements among school principals. In order to inform discussions and decisions among policymakers, researchers, and parents, the 2008-09 Principal Follow-up Survey (PFS)…

This report provides national data on the availability and use of educational technology among teachers in public elementary and secondary schools during the winter and spring of 2009. The data are the results of a national teacher-level survey that is one of a set that includes district, school, and teacher surveys on educational technology.…

The GED[R] English as a Second Language (GED ESL) Test was designed to serve as an adjunct to the GED test battery when an examinee takes either the Spanish- or French-language version of the tests. The GED ESL Test is a criterion-referenced, multiple-choice instrument that assesses the functional, English reading skills of adults whose first…

This discussion paper represents one of the National Association for College Admission Counseling's (NACAC's) first post-Testing Commission steps in advancing the knowledge base and dialogue about test preparation. It describes various types of test preparation programs and summarizes the existing academic research on the effects of test…

Accurate assessment of attitudes about intimate partner violence is important for evaluation of prevention and early intervention programs. Assessment of attitudes about cross-gender interactions is particularly susceptible to bias because it requires specifying the gender of the perpetrator and the victim. As it is likely that respondents will…

In behavioral research, interest is often in examining the degree to which the effect of an independent variable X on an outcome Y is mediated by an intermediary or mediator variable M. This article illustrates how generalized estimating equations (GEE) modeling can be used to estimate the indirect or mediated effect, defined as the amount by…

This paper uses a new survey of graduates from one large civil university in the UK to examine the determinants of over-education and its subsequent impact on labour market earnings. Multiple measurements of over-education were collected to assess the effect of measurement error on the estimated pay penalty associated with over-education. Panel…

A psychological measurement model provides an explicit definition of (a) the theoretical and (b) the numerical relationships between observed scores and the latent variables that underlie the observed scores. Examination of the metric invariance of a measurement model involves testing the hypothesis that all components of the model relating…

In this brief note, the author argues against the use of squared correlation coefficients as measures of explained variance. (JKS)

Discusses the controversy over the limits that scales of measurement impose on the statistical procedures on the statistical procedures we may apply, using the measurement-theoretic concept of meaningfulness in the analysis of these limits. (RB)

A paradoxical implication of Kraemer's expression for the large-sample standard error of Brogden's form of the biserial correlation is identified, and a new expression is given which does not imply the paradox. However, numerical evidence is presented which calls into question the correctness of the expression. (Author)

A nonmetric coordinate adjustment technique determining scale values for objects whose interobject intervals (differences in subjective value) have been directly compared is developed. In Monte Carlo simulations, the degree of metric determinancy of the scale values appears quite high even when the amount of error is relatively high. (Author/JKS)
