Összefoglaló	Straussian Grounded Theory is a systematic qualitative methodology developed by Anselm Strauss and Juliet Corbin that generates theory inductively from data through structured coding procedures. Unlike exploratory description, it aims to produce a substantive mid-range theory that explains how a social process unfolds, grounding every theoretical claim directly in empirical evidence collected from participants who have experienced the phenomenon under study.	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.	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.
