I need help answering this question and coming up with a research question…
Here is the question I need help with:
After reviewing the difference between naturalistic observation and survey research, I need help creating a research question that could be answered by either research method. Also, how the research question I created could be answered using the naturalistic observation approach and, alternatively, by using the survey research method. Also, which would I think would be more effective for my research question?
