The use of different types of research design as the point of departure is a different and very helpful approach to take, especially since many textbooks confuse issues of method and design. The author outlines with great clarity a wide variety of issues, including testing theories, causation, data analysis, and the main considerations involved in using the different research designs covered. Both students and their instructors will find this an extremely valuable, well-written book' - Professor Alan Bryman, University of Loughborough`A wonderful opportunity for research design students and practitioners to think more about the planning and process of research design' - Forum for Qualitative Social ResearchThis book is intended to show social science students the importance of attending to design issues when undertaking social research. One of the main problems in doing practical research is that design and structure are inappropriate for the uses of research. They often do not support the conclusions that are drawn from it. Several research methods books focus on data collection strategy and statistical analysis. While these issues are pertinent, this book argues that the core of research methods is the structure and design of the research. The book:- provides students with a clear understanding of the importance of research design and its place in the research process.- describes the main types of research designs in social research.- explains the logic and purposes of design to enable students to evaluate particular research strategies- equips students with the design skills to operate in real world research situationsThe book is divided into five parts. Part One explores issues about types of research, research concepts, research questions, causality and basic issues in the design process. The remaining four parts focus on different types of research design. Experimental, longitudinal, cross-sectional and case-study methods are clearly and systematically examined, and their strengths and weaknesses are described.The result is a one-stop critical guide to design in social research that students and researchers will find invaluable. 298 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -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. 262 pp. Englisch.
