Quantitative research is a formal, objective, systematic process in which numerical data are used to obtain information about the world. This research method is used to describe variables, examine relationships among variables, and determine cause-and-effect interactions between variables. The qualitative research method of phenomenology allows understanding of the lived experience and the meaning it engenders. The aim of phenomenology is to explore an experience as it is lived by the study participants and interpreted by the researcher. Evidence-based practice is the conscientious integration of best research evidence with clinical expertise and patient values and needs in the delivery of quality, cost-effective health care. It provides the basis for policy decisions and for voluntary change in individual nursing practice. Nursing style is a matter of personal choice.
