What is political science?
the branch of knowledge that deals with the state and system of government; the scientific analysis of political activity and behaviour is the political science. Political science is methodologically diverse and appropriates many methods originating in social research. Approaches include positivism, interpretivism, rational choice theory, behaviouralism, structuralism, post-structuralism, realism, institutionalism, and pluralism. Political science, as one of the social sciences, uses methods and techniques that relate to the kinds of inquiries sought: primary sources such as historical documents and official records, secondary sources such as scholarly journal articles, survey research, statistical analysis, case studies, experimental research, and model building.
