Referring to your own research proposal, what ethical situations and considerations may arise

Over the last several weeks we have discussed the various research designs: how they can be used and why they can and cannot be used in specific situations. Referring to your own research proposal, what ethical situations and considerations may arise? How would they have to be handled? In responding to your peers’ posts, is it possible that they have overlooked something? Discuss what this may be (in a helpful and friendly tone, of course) and suggest solutions.
