This book explores the core principles, related theories, and conventions of qualitative research methods within the field of argumentation studies. In each chapter, contributors identify and contextualize various issues that a qualitative researcher in Argumentation is likely to encounter, and offer clear solutions. In doing so, the book provides a set of guidelines, instruments, and recommendations that enable readers to effectively conduct research and analyze arguments. Furthermore, the book presents discussions of the ethics, validity, and reliability of qualitative research methods, as well as the intersections between qualitative and quantitative approaches. Looking to the future, chapters explore what the field could learn from other disciplines and how research could better integrate alternative data sources. Providing a detailed outline of qualitative data analysis and interpretation, this book will be of interest to scholars and students in the fields of argumentation studies, communication studies, rhetoric, and linguistics.
