You have to structure your thesis topic in the form of a testable hypothesis. If you select a quantitative hypothesis, you may want to follow this example: If unemployment rates increase (as measured by Department of Labor data), then crime increases (as measured by the Uniform Crime Reports data). You may, however, want to do a qualitative test of your thesis hypothesis. This is entirely permissible and easily accomplished. In other words, the method (quantitative or qualitative) is your choice.
