It focuses on exploring issues, generating hypotheses, and understanding phenomena in context rather than testing predetermined hypotheses. This document provides an overview of different qualitative research methods including basic interpretive studies, phenomenological studies, grounded theory studies, case studies, ethnographic studies, narrative analysis, critical qualitative research, and postmodern research.
