Steps for Developing a Research Question
The steps for developing a research question, listed below, can help you organize your thoughts.
Step 1: Pick a topic (or consider the one assigned to you).
Step 2: Write a narrower/smaller topic that is related to the first.
Step 3: List some potential questions that could logically be asked in relation to the narrow topic.
Step 4: Pick the question that you are most interested in.
Step 5: Change that question you’re interested in so that it is more focused.
