Multiple paradigms of nursing science. 0 Qualitative studies utilize inductive reasoning while quantitative studies apply deductive logic (p. 10). Qualitative Research Quantitative Research Objective/Purpose To gain an understanding of underlying reasons and motivations To uncover prevalent trends in thoughts and opinions To quantify data and generalize results from a sample to the population of interest Sometimes followed by qualitative research to explore findings further These assumptions typically apply to data characteristics such as distributions, correlational trends, and the type of variable, to name a few. For example, asking people to report their criminal behavior in a survey may not be as reliable as asking people to report their eating habits.
