Statistics in Psychology covers all statistical methods needed in education and research in psychology. This book looks at research questions when planning data sampling, that is to design the intended study and to calculate the sample sizes in advance. In other words, no analysis applies if the minimum size is not determined in order to fulfil certain precision requirements. The book looks at the process of empirical research into the following seven stages: Formulation of the problem Stipulation of the precision requirements Selecting the statistical model for the planning and analysis The (optimal) design of the experiment or survey Performing the experiment or the survey Statistical analysis of the observed results Interpretation of the results.

This volume is based on an international conference held at the Institute for Science Education (IPN) in Kiel in August 1985. The IPN is a national research institute for science education of the Federal Republic of Germany associated with the University of Kiel. The aim of this conference-to treat latent trait and latent class models under comparative points of view as well as under application aspects-was realized in many stimulating contributions and very different ways. We asked the authors of these papers to work out their contributions for publication here, not only because many of the papers present new material, but also because the time is ripe for a comprehen sive volume, working u...
Leading experts describe the state-of-the-art in developing and constructing psychometric tests This latest volume in the series Psychological Assessment – Science and Practice describes the current state-of-the-art in test development and construction. The past 10-20 years have seen substantial advances in the methods used to develop and administer tests. In this volume many of the world's leading authorities collate these advances and provide information about current practices, thus equipping researchers and students to successfully construct new tests using the best modern standards and techniques. The first section explains the benefits of considering the underlying theory when designing tests, such as factor analysis and item response theory. The second section looks at item format and test presentation. The third discusses model testing and selection, while the fourth goes into statistical methods that can find group-specific bias. The final section discusses topics of special relevance such as multi-trait multi-state analyses and development of screening instruments.
Psychological testing has grown exponentially as technological advances have permitted it to and societal complexities have necessitated its growth. Psychological testing or psychological assessment is a field characterised by the use of samples of behaviour in order to infer generalisations about a given individual. By samples of behaviour, one means observations over time of an individual performing tasks that have usually been prescribed beforehand. These responses are often compiled into statistical tables that allow the evaluator to compare the behaviour of the individual being tested to the responses of a norm group. The broad categories of psychological evaluation tests include: Norm-referenced, IQ/achievement tests, Neuropsychological tests, Personality tests, Objective tests (Rating scale), Direct observation tests, Psychological evaluations using data mining. New and important research is presented in this book.
First multi-year cumulation covers six years: 1965-70.
This book examines extensions of the Rasch model, one of the most researched and applied models in educational research and social science. This collection contains 22 chapters by some of the most renowned international experts in the field. They cover topics ranging from general model extensions to applications in fields as diverse as cognition, personality, organizational and sports psychology, and health sciences and education.

Die Testbatterie Adaptives Intelligenz Diagnostikum (AID) dient der Erfassung komplexer und basaler intellektueller Fähigkeiten bei Kindern und Jugendlichen im Alter von 6;0 bis 15;11 Jahren. Das umfangreiche Testmaterial erlaubt es, einen weit gestreckten Fähigkeitsbereich eindimensional zu messen, wobei aufgrund der adaptiven Testvorgabe besonders testökonomisch verfahren wird. Neben der globalen Beurteilung der Intelligenz und der Profilinterpretation ermöglicht das Verfahren auch ein Screening in Bezug auf ausgewählte Teilleistungsfähigkeiten. Die Verfügbarkeit sprachfreier Instruktionen erweitert die Einsatzmöglichkeiten des Verfahrens. Dieses Fallbuch richtet sich an Praktiker ...
