Sociology is a branch of social science that involves the study of human social relationships, social behavior and the society, including its origins, development, organization, networks, and institutions. Students who gain an expertise in sociology know how to think critically about human social life, and how to ask important questions. They develop the skill of designing good social research projects, meticulously collecting and analyzing empirical data along with formulating and presenting their research findings. They also become adept at helping others understand the way the social world works and how it could be changed for the better.
