The second edition of this widely used text provides a comprehensive introduction to the main research methods employed in the study of politics and assessment of their strengths and limitations; of their interrelationship; and of ethical issues in research. Illustrated throughout with boxed examples of real political research, the book ranges widely from substantial coverage of statistical methods to the use of archives, interviews, discourse analysis and the internet. Two additional chapters in the second edition focus on the relationship between research and policy and the lessons for researchers from the study of elections in the US and UK.
