Yesterday, qualitative and quantitative methodologies were discussed. Creswell (2016) has a more in-depth description of both here:
Research methodologies also have research designs to integrate a logical cycle of studying the research question. Depending on your doctoral institution and/or discipline, the research design addresses the problem statement via research questions; as well as how data is collected and analyzed.
Which one best suits your research study? Tomorrow, we’ll explore how your problem statement will guide that choice.
