خلاصه	Conversation Analysis (CA) is a qualitative research method that examines the fine-grained sequential structure of naturally occurring talk and social interaction. Developed by sociologists Harvey Sacks, Emanuel Schegloff, and Gail Jefferson in the 1960s and 1970s, CA investigates how participants in a conversation accomplish social actions — such as invitations, refusals, or diagnoses — through the precise moment-by-moment organisation of their talk, including turn-taking, sequence structure, repair, and recipient design.	Content analysis is a systematic research technique for reducing text, visual, or media material into coded categories so that patterns can be counted, compared, and interpreted. Formalised by Klaus Krippendorff in his widely cited methodology textbook (latest edition 2018), the method sits at the boundary of qualitative and quantitative inquiry: it imposes structured, replicable coding on inherently meaning-laden material.	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.
