The unique emphasis of this book is on the “how-to”—that is, the set of conceptual and active tasks carried out by mixed methods researchers—illustrated with rich case studies, primarily from the authors’ own policy research and programme evaluation work. The challenges that both beginners and advanced scholars encounter when doing mixed methods research and the kinds of practical tools available are examined. All of the chapters conclude with questions that help readers to integrate and apply concepts and techniques to their own work.
