A Theory of Group Structures Volume II: Empirical Tests

An Introduction to Psychometrics and Psychological Assessment Using Interpreting and Developing Tests

An Introduction to Psychometrics and Psychological Assessment Using Interpreting and Developing Tests

An Introduction to Psychometrics and Psychological Assessment is the successor to Cooper’s prize-winning book Psychological Testing: Theory and Practice. This expanded and updated volume shows how psychological questionnaires and tests can be chosen administered scored interpreted and developed. In providing students researchers test users test developers and practitioners in the social sciences education and health with an evaluative guide to choosing using interpreting and developing tests it provides readers a thorough grasp of the principles (and limitations) of testing together with the necessary methodological detail. This book has three distinctive features. First it stresses the basic logic of psychological assessment without getting bogged down with mathematics; the spreadsheet simulations and utilities which are integrated into the text allow users to explore how numbers behave rather than reading equations. Readers will learn by doing. Second it covers both the theory behind psychological assessment and the practicalities of locating designing and using tests and interpreting their scores. Finally it is evaluative. Rather than just describing concepts such as test reliability or adaptive testing it stresses the underlying principles merits and drawbacks of each approach to assessment and methods of developing and evaluating questionnaires and tests. Unusually for an introductory text it includes coverage of several cutting-edge techniques and this new edition expands the discussion on measurement invariance methods of detecting/quantifying bias and hierarchical factor models and features added sections on: Best practices for translation of tests into other languages and problems of cultural bias Automatic item generation The advantages drawbacks and practicalities of internet-based testing Generalizability theory Network analysis Dangerous assumptions made when scoring tests The accuracy of tests used for assessing individuals The two-way relationship between psychometrics and psychological theory Aimed at non-mathematicians this friendly and engaging text will help you to understand the fundamental principles of psychometrics that underpin the measurement of any human characteristic using any psychological test. Written by a leading figure in the field and accompanied by additional resources including a set of spreadsheets which use simulated data and other techniques to illustrate important issues this is an essential introduction for all students of psychology and related disciplines. It assumes very little statistical background and is written for students studying psychological assessment or psychometrics and for researchers and practitioners who use questionnaires and tests to measure personality cognitive abilities educational attainment mood or motivation. | An Introduction to Psychometrics and Psychological Assessment Using Interpreting and Developing Tests

Statistical Power Analysis A Simple and General Model for Traditional and Modern Hypothesis Tests Fifth Edition

Statistical Power Analysis A Simple and General Model for Traditional and Modern Hypothesis Tests Fifth Edition

Statistical Power Analysis explains the key concepts in statistical power analysis and illustrates their application in both tests of traditional null hypotheses (that treatments or interventions have no effect in the population) and in tests of the minimum-effect hypotheses (that the population effects of treatments or interventions are so small that they can be safely treated as unimportant). It provides readers with the tools to understand and perform power analyses for virtually all the statistical methods used in the social and behavioral sciences. Brett Myors and Kevin Murphy apply the latest approaches of power analysis to both null hypothesis and minimum-effect testing using the same basic unified model. This book starts with a review of the key concepts that underly statistical power. It goes on to show how to perform and interpret power analyses and the ways to use them to diagnose and plan research. We discuss the uses of power analysis in correlation and regression in the analysis of experimental data and in multilevel studies. This edition includes new material and new power software. The programs used for power analysis in this book have been re-written in R a language that is widely used and freely available. The authors include R codes for all programs and we have also provided a web-based app that allows users who are not comfortable with R to perform a wide range of analyses using any computer or device that provides access to the web. Statistical Power Analysis helps readers design studies diagnose existing studies and understand why hypothesis tests come out the way they do. The fifth edition includes updates to all chapters to accommodate the most current scholarship as well as recalculations of all examples. This book is intended for graduate students and faculty in the behavioral and social sciences; researchers in other fields will find the concepts and methods laid out here valuable and applicable to studies in many domains. | Statistical Power Analysis A Simple and General Model for Traditional and Modern Hypothesis Tests Fifth Edition

Statistics in Corpus Linguistics Research A New Approach

Statistics in Corpus Linguistics Research A New Approach

Traditional approaches focused on significance tests have often been difficult for linguistics researchers to visualise. Statistics in Corpus Linguistics Research: A New Approach breaks these significance tests down for researchers in corpus linguistics and linguistic analysis promoting a visual approach to understanding the performance of tests with real data and demonstrating how to derive new intervals and tests. Accessibly written this book discusses the ‘why’ behind the statistical model allowing readers a greater facility for choosing their own methodologies. Accessibly written for those with little to no mathematical or statistical background it explains the mathematical fundamentals of simple significance tests by relating them to confidence intervals. With sample datasets and easy-to-read visuals this book focuses on practical issues such as how to: • pose research questions in terms of choice and constraint; • employ confidence intervals correctly (including in graph plots); • select optimal significance tests (and what results mean); • measure the size of the effect of one variable on another; • estimate the similarity of distribution patterns; and • evaluate whether the results of two experiments significantly differ. Appropriate for anyone from the student just beginning their career to the seasoned researcher this book is both a practical overview and valuable resource. | Statistics in Corpus Linguistics Research A New Approach

Statistical Methods An Introduction to Basic Statistical Concepts and Analysis

Statistical Methods An Introduction to Basic Statistical Concepts and Analysis

Statistical Methods: An Introduction to Basic Statistical Concepts and Analysis Second Edition is a textbook designed for students with no prior training in statistics. It provides a solid background of the core statistical concepts taught in most introductory statistics textbooks. Mathematical proofs are deemphasized in favor of careful explanations of statistical constructs. The text begins with coverage of descriptive statistics such as measures of central tendency and variability then moves on to inferential statistics. Transitional chapters on z-scores probability and sampling distributions pave the way to understanding the logic of hypothesis testing and the inferential tests that follow. Hypothesis testing is taught through a four-step process. These same four steps are used throughout the text for the other statistical tests presented including t tests one- and two-way ANOVAs chi-square and correlation. A chapter on nonparametric tests is also provided as an alternative when the requirements cannot be met for parametric tests. Because the same logical framework and sequential steps are used throughout the text a consistency is provided that allows students to gradually master the concepts. Their learning is enhanced further with the inclusion of thought questions and practice problems integrated throughout the chapters. New to the second edition: Chapters on factorial analysis of variance and non-parametric techniques for all data Additional and updated chapter exercises for students to test and demonstrate their learning Full instructor resources: test bank questions Powerpoint slides and an Instructor Manual | Statistical Methods An Introduction to Basic Statistical Concepts and Analysis
