Designing Social Inquiry: Scientific Inference in Qualitative Research Gary King, Robert O. Keohane, and Sidney Verba is an English-language study book about quantitative and qualitative research methods in the social sciences. This reference work offers a coherent approach to research and scientific inference.
The book addresses the principles of social inquiry, including formulating research questions, measuring data accuracy, and discovering causal relationships. It explains how both qualitative and quantitative research follow the same logic of scientific inference. Topics such as interpretation, comparative case studies, the construction of causal theories, and measurement errors are covered in depth. Mathematical notations are used only for clarification and do not require prior knowledge.
This new edition includes a foreword by the authors and is a valuable resource for students and professionals who focus on qualitative research within political science and social methodology.
