This book takes a fresh look at applying regression analysis in the behavioural sciences by introducing the reader to regression analysis through a simple model-building approach. The authors start with the basics and begin by re-visiting the mean, and the standard deviation, with which most readers will already be familiar, and show that they can be thought of a least squares model. The book then shows that this least squares model is actually a special case of a regression analysis and can be extended to deal with first one, and then more than one independent variable. Extending the model from the mean to a regression analysis provides a powerful, but simple, way of thinking about what students believe are the more complex aspects of regression analysis. The authors gradually extend the model to include aspects of regression analysis such as non-linear regression, logistic regression, and moderator and mediator analysis. These approaches are often presented in terms that are too mathematical for non-statistically inclined students to deal with. Throughout the book maintains a conceptual, non-mathematical focus. Most equations are placed in an appendix, where a detailed explanation is given, to avoid disrupting the flow of the main text. This book will be indispensable for anyone using regression and correlation from undergraduates doing projects to postgraduate and researchers.

Sebastian Eberz entwickelt „FSim“ als interaktive, Szenario-basierte Computersimulation, die effektuatives und kausales Verhalten in einer virtuellen Umgebung zulässt und erfassbar macht. Es wird gezeigt, dass der Effectuation-Ansatz als moderne Entrepreneurship-Theorie und Alternative zum traditionellen Ansatz (Causation) bislang nur ansatzweise die Rolle der Persönlichkeit für das Gründungsverhalten adressierte. Zudem stehen vor allem erfahrene Entrepreneure im Vordergrund. Die durchgeführte theoretische Analyse und eine empirische Studie zeigen jedoch, dass auch unerfahrene Entrepreneure grundlegend effektuatives und kausales Verhalten aufweisen, das von der Persönlichkeit in Abhängigkeit von der Umgebungsunsicherheit beeinflusst wird.

Wie Meinungsführer Meinung kommunizieren

Meinungsführerschaft in der politischen Alltagskommunikation

Meinungsführer gelten als Personen, die in politischen Gesprächen die Meinungen ihrer Mitmenschen beeinflussen können. Bis dato wissen wir jedoch nur wenig über die Kommunikation von Meinungsführern und damit darüber, wie sie ihre Gesprächspartner beeinflussen. Um Meinungsführerschaft und damit kommunikative Einflussnahme in politischen Alltagsgesprächen zu untersuchen, führt Sarah Geber in ihrer Dissertationsschrift kommunikationswissenschaftliche und sozialpsychologische sowie -linguistische Erkenntnisse in einem Modell zur Meinungsführerschaft in der politischen Alltagskommunikation zusammen. Zur Überprüfung des Modells wurden Freundschafts- und Bekanntschaftspaare befragt und deren politische Gespräche beobachtet. Die Ergebnisse zeigen, dass Meinungsführerschaft ein inhaltlich und sozial relevantes Phänomen politischer Alltagskommunikation ist. Meinungsführerschaft zeigt sich zwar weniger in einer bedeutenden Beeinflussung der Meinung der Gesprächspartner, jedoch in einer argumentativ gestützten und damit deliberativ relevanten Meinungskommunikation. Die soziale Bedeutung des Phänomens manifestiert sich zum einen im Ziel, sich der Rolle des Meinungsführers entsprechend als kompetent und meinungsstark darstellen zu wollen, und zum anderen in der sozialen Anerkennung der Meinungsführerrolle durch den Gesprächspartner. Die Studie schließt eine bedeutsame Forschungslücke der Meinungsführerforschung und gibt einen gesellschaftlich relevanten Einblick in die politische Alltagskommunikation.

Presenting topics in the form of questions and answers, this popular supplemental text offers a brief introduction on multiple regression on a conceptual level. Author Paul D. Allison answers the most essential questions (such as how to read and interpret multiple regression tables and how to critique multiple regression results) in the early chapters, and then tackles the less important ones (for instance, those arising from multicollinearity) in the later chapters. With this organization, readers can stop at the end of any chapter and still feel like they've already gotten the meat of the subject.

WINNER OF THE 2007 BRITISH PSYCHOLOGICAL SOCIETY BOOK AWARD 2007 'It is noteworthy that after I used some of the illustrations and mentioned the book in class, most students went and bought a copy. Their final papers were heavily "Field-referenced"! That is the best endorsement one can give to a text' - Journal of Advanced Nursing 'The wide range of statistical techniques covered combined with good accompanying background explanations, communicated in a relaxed, affable style, make this book a useful addition to the bookshelves of both practitioners and teachers of statistics alike in the social sciences' - Peter Watson, MRC Cognition and Brain Sciences Unit, Cambridge and Chair of ASSESS, Independent European Group of SPSS Users 'The Second Edition of Andy Field's Discovering Statistics Using SPSS is an excellent book and a valuable addition to the teaching of statistics in the behavioral sciences. The title of the book accurately reflects the approach taken. This is not simply a primer on how to use SPSS, but is a very good statistics text using SPSS as a vehicle for illustrating and expanding on the statistical content of the book. At the same time it also serves as a manual for SPSS, and has taught me things that I had not known about the software. One advantage of the text is that it is not tied specifically to the latest version of SPSS. Although the examples use version 12.0, there are many references to the difference the students will find if they are using an earlier version. A good example of how the text is structured can be seen in Chapters 8 and 9. Chapter 8 provides an introduction to the analysis of variance, and roughly the first 40 pages are devoted to statistical issues. Only after that introduction does the author move to a discussion of using SPSS to run the analyses. Chapter 9 deals with the analysis of covariance, and here the author moves almost immediately to SPSS printout, having laid most of the groundwork in the previous chapter. I find this flexible approach to the blending of content and software to be an effective way of teaching the material. It is impossible to review this book without commenting on Andy's particular style. I enjoyed it immensely and think that it would appeal to both students and their instructors. It is refreshing to see someone who doesn't take himself too seriously' - David C Howell, Professor Emeritus, University of Vermont 'The new edition of Field's textbook confirms its place as the best statistics text for undergraduate social science students. It provides support for those less confident about statistical analysis whilst having sufficient depth that it will still be valuable to more mathematically experienced people. There is a focus throughout on the practical aspects of data analysis and interpretation whilst at the same time emphasizing the importance of rigour and a good understating of theory essential reading' - Dr Ian Walker, Department of Psychology, University of Bath 'Very useful, valuable and interesting. Summing up: Highly recommended' - CHOICE, Current Reviews for Academic Librarians This new edition of Field's textbook provides students of statistical methods with everything they need to understand, use and report statistics - at every level. Written in Andy Field's vivid and entertaining style, and furnished with playful examples from everyday student life (among other places), the book forms an accessible gateway into the often intimidating world of statistics and a unique opportunity for students to ground their knowledge of statistics through the use of SPSS.

Introducing Anova and Ancova

A GLM Approach

View: 9783

Traditional approaches to ANOVA and ANCOVA are now being replaced by a General Linear Modeling (GLM) approach. This book begins with a brief history of the separate development of ANOVA and regression analyses and demonstrates how both analysis forms are subsumed by the General Linear Model. A simple single independent factor ANOVA is analysed first in conventional terms and then again in GLM terms to illustrate the two approaches. The text then goes on to cover the main designs, both independent and related ANOVA and ANCOVA, single and multi-factor designs. The conventional statistical assumptions underlying ANOVA and ANCOVA are detailed and given expression in GLM terms. Alternatives to traditional ANCO
