Qualitative research helps to understand human experience and meaning within a given context using text rather than numbers, interpreting experience and meaning to generate understanding, and recognizing the role of the researcher in the construction of knowledge. A useful description of qualitative research is as follows: ‘Qualitative research begins with assumptions, a worldview, the possible use of a theoretical lens, and the study of research problems inquiring into the meaning individuals or groups ascribe to a social or human Epacadostat problem. To study this problem, qualitative researchers use an emerging

qualitative approach to inquiry, the collection of data in a natural setting sensitive to the people and places under study, and data analysis is inductive and establishes patterns or themes. The final written report or presentation includes the voices of participants, the reflexivity of the researcher, and a complex description and interpretation of the problem, and it extends the literature or signals a call for action.’ ( Creswell, 2007, p. 37) The purpose of this paper is to explore the underpinning philosophy behind qualitative research and to help do this, some comparisons will be made to quantitative research. It is possible that readers only familiar with quantitative research may actually be relatively unaware of their ontological

and epistemological assumptions. They are so taken for granted that they are often not explicitly stated in research papers. Two very different paradigms, or theoretical frameworks, positivism/post-positivism and interpretivism

buy Y-27632 commonly (but not always) underpin quantitative and qualitative research respectively and are summarised in Table 4. Before launching into each paradigm it may be useful to define terms. Ontology is used here to refer to the nature of reality. It is the claims or assumptions that a particular approach makes about the nature of the reality under investigation (Blaikie, 1993). Epistemology is used here to refer to the ways in which it is possible to gain knowledge of this reality. It is the claims or assumptions about how that reality can be made known (Blaikie, 1993). An epistemology is a theory of knowledge of what can be known and what criteria it uses to justify it being knowledge. This paradigm Liothyronine Sodium (also known as the scientific method or empirical science) developed during the enlightenment in the eighteenth century when rational thought and reason replaced religion and faith to explain phenomena. It assumes a stable reality that can be measured and observed in a rigorous and systematic way to develop objective knowledge (facts). Ontologically, it assumes a single objective reality. Social reality is considered a complex result of causal relations between events, with the cause of human behaviour external to the individual.
