Coding Qualitative Data

Coding is the process of assigning short labels, or codes, to segments of qualitative material such as interview transcripts, field notes, or documents. Each code captures what a segment is about, allowing the researcher to group related passages, compare them across sources, and build toward broader categories or themes. Coding can be inductive, with codes emerging from the data, or deductive, with codes drawn from an existing framework, and it usually proceeds through several cycles of refinement.

In a thesis, coding is what turns hundreds of pages of raw transcripts into findings you can actually report. A transparent coding process, documented in your methodology chapter with examples of codes and how they were developed, shows examiners that your themes rest on systematic analysis rather than selective quotation.
