สรุป	In vivo coding is a qualitative first-cycle coding strategy in which the researcher uses the participants' own words or short phrases verbatim as code labels, rather than imposing researcher-generated or theoretical language. The technique preserves the voice, meaning, and conceptual priorities of participants, making it especially valuable in grounded theory, phenomenology, and any study where honouring the emic (insider) perspective is central to analytic integrity.	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.
