I have a question about the formulation of hypothesis in an ethnographic research? i read a couple of books and found opposing views. In her discussion of participant-observation method, Schilling Estes (2013) says that we can "consider what we observe, formulating and reformulating hypotheses, then return back to the community for more focused observations based on our ever more finely tuned hypotheses" (p. 117), whereas Eckert (2000) notes that “Rather than testing hypotheses against predetermined categories, ethnography is, among other things, a search for local categories. Thus while survey fieldwork focuses on filling in a sample, ethnographic fieldwork focuses on finding out what is worth sampling.”. I am a bit confused which one is more suitable for an ethnographic fieldwork in a sociolinguistic study? to proceed with research questions or to formulate a testable hypothesis right from the scratch?
