Резюме	Biographical research is a qualitative method that examines individual lives in depth — through life-history interviews, personal documents, letters, and autobiographical narratives — to understand how personal experience intersects with social, historical, and cultural forces. Rooted in Wilhelm Dilthey's hermeneutics and made prominent in sociology by Thomas and Znaniecki's study of Polish immigrants, it treats the individual life story as a window onto broader social structures and processes. It belongs to the narrative inquiry subfamily alongside oral history and life-story research.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.	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.
