Dear Guru, your post is a bit confusing to me, as you say that you are "in the stage of preparing Research Data...." What do you mean by completed coursework? Where are you pursuing your Ph.D., and in what mode? What are your aims, objectives, and hypotheses? Before arriving at these, have you not done the literature survey to see what others have done, how, and why in that way? If you have, did you not come across any questionnaires used by others?
If you have not covered Research Methodology in any depth, please see my thread on that topic at CiteHr; I have attached a PowerPoint slide presentation.
Have a nice day.
