सारांश	Life history research is a qualitative method that captures the full arc of an individual's life — or a significant portion of it — through extended biographical interviewing and analysis of personal documents. Rooted in early Chicago School sociology, the method treats each life story as a window into broader social, cultural, and historical forces. The researcher and participant co-construct a narrative account that illuminates how personal experience is shaped by, and in turn shapes, wider social structures and processes.	Ethnography is a qualitative research tradition in which a researcher immerses themselves in a social group or community over an extended period — typically three to six months or longer — to study its culture, values, and behaviours in their natural setting. Originating in social and cultural anthropology, and consolidated as a rigorous method by Bronisław Malinowski in the early twentieth century, ethnography produces rich, contextualised accounts of how people live, work, and make meaning together.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
