Interviews involve asking people questions that are open ended- that is,you haven't predetermined possible answer choice for them. instead, they freely express themselves in answering your questions. their answers are not analyzed with statistics, but instead are analyzed for their meaning and themes. the purpose of interviews is to better understand some aspect of the social world from the perspective in great depth. interviews yield very detailed information about the perspectives of only a small group of people. they are best used for studying what goes on in people's head: their perceptions, interpretations,meanings and experiences of the social world,as well as their motivations and feelings.
