সারসংক্ষেপ	Comparative biographical research is a qualitative design that gathers in-depth life-story accounts from multiple participants and systematically compares them to identify structural patterns, commonalities, and divergences across individual biographies. Rooted in the sociological life-history tradition, it moves beyond single-case description to generate broader theoretical insights about how social conditions, historical contexts, and personal agency shape individual trajectories.	Comparative case study is a qualitative research design in which two or more bounded cases are studied in depth and then systematically compared to identify similarities, differences, and patterns across contexts. Rooted in Yin's replication logic and Stake's multiple case framework, it is particularly suited to questions that ask how or why a phenomenon unfolds differently — or similarly — across distinct settings, populations, or time periods.
