Even if you used a quantitative research design, but failed to employ a probability sampling technique, there are still many perfectly justifiable reasons why you could have made such a choice.

Writing a psychology dissertation in this area may prove enjoyable for the author, as well as the reader.
13. Include a title on your proposal. I'm amazed at how often the title is left for the end of the student's writing and then somehow forgotten when the proposal is prepared for the committee.

It's easy for a reader to identify those proposals where the title has been focused upon by the student. Preparing a good title means:
