Finding Patterns in Words, Not Numbers
Analyzing qualitative data — interview transcripts, open-ended responses, field notes — requires systematic methods of its own, distinct from statistical analysis of numbers. Thematic analysis, one of the most widely used approaches (formalized by Virginia Braun and Victoria Clarke), typically proceeds through a structured sequence: familiarizing oneself with the data, generating initial codes (labels marking meaningful segments of text), searching for broader themes among those codes, reviewing and refining candidate themes, clearly defining and naming each final theme, and writing up the analysis with illustrative quotes.
Coding itself can proceed in different ways: open coding applies labels to the data with minimal preconceived categories, staying close to what is actually present, while axial coding (used especially in grounded theory) looks for relationships and connections BETWEEN the codes generated during open coding, building toward a more integrated structure.
| Stage/Concept | What it involves |
|---|---|
| Open coding | Labeling data with minimal preconceived categories |
| Axial coding | Finding relationships between codes |
| Theme | A broader pattern uniting related codes |
Grounded theory (Barney Glaser and Anselm Strauss) is a distinctive qualitative approach in which theory is built INDUCTIVELY, emerging FROM the data through this coding process, rather than being formulated in advance and then tested against the data (the more typical, DEDUCTIVE approach in much quantitative research). This makes grounded theory especially well suited to genuinely novel or under-studied phenomena, where an existing theoretical framework may not yet exist to test.
Just as in quantitative research, qualitative analysis benefits from checking inter-rater reliability: having multiple independent researchers code the same material and comparing their codes for agreement, which helps guard against one researcher's idiosyncratic interpretation dominating the analysis.
Common pitfall: assuming qualitative coding is a purely subjective, "anything goes" free-for-all with no rigor at all. Systematic procedures (explicit coding schemes, checking inter-rater reliability, actively searching for evidence that contradicts an emerging theme) are exactly what distinguish careful qualitative analysis from casual, unsystematic impression.
