What is (at least) one major difference between quantitative and qualitative approaches?What types of research questions are better studied using quantitative approaches and what types are better studied with qualitative approaches?Good research convinces us that something is true. Discuss why researchers often build their arguments using BOTH correlational evidence (showing an IV and DV co-vary across cases) and process-tracing evidence (showing the logical sequence of events by which changes in an IV cause changes in a DV).
