This new edition has been sustantially revised and updated, and provides a comprehensive survey of current research methods in psychology today, clearly explaining statistical concepts and procedures. The full range of common experimental and non-experiemental methods are covered in depth, along with an integration of the contemporary qualitative-quantitative debate among psychological researchers. Additions in the qualitative arena include discussions on discursive psychology, reflexivity, verbal protocols and the transcription of recorded speech. In the statistical sections, ANOVA procedures (including multi-factorial designs), multi-level non-parametric tests, and a brief introduction to complex tests (MANOVA, ANCOVA and multiple regression) are all covered, and basic procedural methods have been completely updated. Each chapter deals with a different topic, and ends with an exercise section to test material covered in that chapter. A detailed summary of each chapter and a glossary of key terms, which can be used as a self-test resource, are also included. The ten structured exercises, similar to A-level practical questions, at the end of the book, have been completely revised.
