"Quantitative Psychological Research: A Student's Handbook" expertly guides the reader through all stages involved in undertaking quantitative psychological research, from accessing the relevant literature, through designing and conducting a study, analyzing and interpreting data, and finally reporting the research. This third edition includes two new chapters - on preliminary checking of data and on allowing for additional variables when comparing the means of different conditions - and expands on original topics such as sample sizes and how to test for mediation effects. It also contains increased coverage of tests and further detail of techniques and terms which psychologists will meet when working with those in the medical professions. As the chapters focus on choosing appropriate statistical tests and how to interpret and report them (rather than the detailed calculations, which appear in appendices), the reader is able to gain an understanding of a test without being interrupted by the need to understand the complex mathematics behind it.; The book helps readers to: locate reports of relevant existing research; design research while adhering to ethical principles; identify various methods which can be used to ask questions or observe behaviour; choose appropriate samples; display and analyse findings numerically and graphically to test hypotheses; and, report psychological research in a variety of ways. The book covers the entire syllabus for the quantitative methods section of the Qualifying Exams of the British Psychological Society. It is suitable for psychology students and professionals at all levels, and is particularly useful to those working in Health and Clinical Psychology.
