সারসংক্ষেপ	Field notes are detailed written records created by researchers during or immediately after direct observation in a naturalistic setting. They capture what is seen, heard, and experienced — including behaviors, interactions, physical environments, and the researcher's own analytic impressions — forming the primary data source for ethnographic and observational studies.	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.	Non-participant observation is a data-collection method in which the researcher observes behavior, interactions, or events in a natural or structured setting without joining or influencing the activity under study. The observer maintains a deliberate distance from participants to minimize their own effect on the phenomena being recorded, producing field notes, behavioral tallies, or recordings that reflect naturally occurring behavior rather than behavior shaped by researcher involvement.
