Coding data is a data reduction method. In qualitative research, codes are typically words or devices for identifying themes.
Ryan and Bernard (2000) cite MacQueen, McLellan, Kay and Milstein (1998) when suggesting that a good codebook should include:
- a detailed description of each code
- inclusion and exclusion criteria
- exemplars of real text for each theme
- exemplars of the theme's boundaries, if abstract
Miles and Huberman (1994) provide a very thorough discussion of strategies for coding and sorting segments of data. See particularly chapters 4-9.
