In more detail
An inductive orientation develops codes and themes from the data, without fitting them to a framework decided in advance. A deductive orientation uses existing theory or concepts as a lens for coding and theme development.
In practice the two are often combined, and Braun and Clarke treat them as ends of a spectrum rather than a choice of one or the other. A method section that states the orientation helps readers understand where the themes came from.
In Themescape
The orientation is a choice about the analysis, not the software. A Theoretical connection is one way to mark a link that comes from theory rather than from shared codes in the data.
