The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible. Quantitative and qualitative research methods differ primarily in: • their analytical objectives • the types of questions they pose • the types of data collection instruments they use • the forms of data they produce • the degree of flexibility built into study design Table 1, page 3, briefly outlines these major differences. There are many ways to categorize different types of research.
