Analysing vs interpreting

The instructions say that chapter 4 should be about analysing the data, and chapter 5 interpreting the data. Well, some might say that those words are a bit similar in meaning, so I have to work out where they separate. I'm taking the analysis to be a description in the light of the codes that I've applied. The interpretation is more about explaining what the data reveals, and I'm structuring that interpretation against the roles and what they suggest in answer to the research questions.
