New subtests are described along with tips for accurate administration and...

This new text provides a state-of the-art introduction to educational and psychological testing and measurement theory that reflects many intellectual developments of the past two decades. The book introduces psychometric theory using a latent variable modeling (LVM) framework and emphasizes interval estimation throughout, so as to better prepare readers for studying more advanced topics later in their careers. Featuring numerous examples, it presents an applied approach to conducting test...

Does your IQ really measure your intelligence?Is IQ genetic?Can your IQ vary?Do we get smarter or dumber as we get older?How will IQ tests be different in the future?Dr. Kaufman, a leading expert on the development of IQ tests, explores these critical questions and many more in IQ Testing 101. This book provides a brief, compelling introduction to the topic of IQ testing-its mysteries, misconceptions, and truths....

The twenty-first century has seen a breathtaking expansion of statistical methodology, both in scope and in influence. 'Big data', 'data science', and 'machine learning' have become familiar terms in the news, as statistical methods are brought to bear upon the enormous data sets of modern science and commerce. How did we get here? And where are we going? This book takes us on an exhilarating journey through the revolution in data analysis following the introduction of electronic computati...

In a managed care era, the MMPI-2 is becoming an overloaded workhorse, required to generate more and more of the assessments that a battery of instruments once did. Though all now rely on the MMPI-2 for good reasons, and the MMPI has fallen out of use entirely, some important and clinically useful scales were lost in the transition.Edward Gotts and Thomas Knudsen have recovered these scales and integrated them with all the standard MMPI-2 scales, the recently published Restructured...

A comprehensive resource for assessment practitioners, this book provides step-by-step guidance for developing, administering, scoring, and validating a range of performance tasks, including literacy and other types of proficiency assessments. The authors explore how to establish the purpose of the assessment and how to develop scoring tools, train raters, reduce rater bias, review scores and report results, and use item-level and test-level analyses to optimize reliability and validity. C...

The goal of this guide and manual is to provide a practical and brief overview of the theory on computerized adaptive testing (CAT) and multistage testing (MST) and to illustrate the methodologies and applications using R open source language and several data examples. Implementation relies on the R packages catR and mstR that have been already or are being developed by the first author (with the team) and that include some of the newest research algorithms on the topic.The book co...

Contemporary Psychometrics features cutting edge chapters organized in four sections: test theory, factor analysis, structural equation modeling, and multivariate analysis.The section on test theory includes topics such as multidimensional item response theory (IRT), the relationship between IRT and factor analysis, estimation and testing of these models, and basic measurement issues that are often neglected.The factor analysis section reviews the history and devel...

This book describes how to use test equating methods in practice. The non-commercial software R is used throughout the book to illustrate how to perform different equating methods when scores data are collected under different data collection designs, such as equivalent groups design, single group design, counterbalanced design and non equivalent groups with anchor test design. The R packages equate, kequate and SNSequate, among others, are used to practically illustrate the different meth...
