I'll try for a more detailed listing. Typology - a classification system, taken from patterns, themes, or other kinds of groups of data. Ideally, categories should be mutually exclusive and exhaustive if possible, often they aren't. Basically a list of categories. A sophisticated typology with multiple levels of concepts.
Higher levels are inclusive of lower levels.
Superordinate and subordinate categories 3. So need to categorize specific events We used to cut apart copies of field notes, now use computers. Eventually category saturates when no new codes related to it are formed Eventually certain categories become more central focus - axial categories and perhaps even core category. I wrote a paper on the topic . Look at event and develop a hypothetical statement of what happened.
