In psychology, answers to our questions are not as succinct as in other types of sciences, and the findings essentially depend upon the underlying epistemology used. This essay seeks to define and examine the fields of qualitative and quantitative research. It will address the different epistemologies and methodologies of each paradigm, and aim to give you a brief overview of the two main research methods underlying scientific knowledge.
Qualitative research is often only defined in contrast to Quantitative research; That is, it does not involve statistics, nor does it depend on the level of objectivity that characterises the quantitative approach. While quantitative research aims to categorise participants in numerical form by creating statistical models to answer specific hypothesises; Qualitative research does not start with a specific hypothesis, instead it seeks to understand behaviours, and experiences (McQueen & Knussen, 2013, p.422).
Qualitative researchers tend to operate under different epistemological beliefs than that of quantitative researchers. Unlike quantitative researchers who use fixed instruments with little flexibility, Qualitative researchers allow questions to emanate and reshape themselves as the research unfolds (Krauss, 2005, p. 759). The qualitative researcher is engaged in the world they investigate, creating an unstructured and reflective element to the research, where the researchers’ knowledge, emotive interactions, and past experiences all form a part of the research (Ponterotto, 2010, p.583).
According to Guba and Lincoln (as cited in Ponterotto, 2005, p.128) there are four main research paradigms: postpositivism, constructivism-interpretivism and the critical-ideological and positivism perspective. Of these four paradigms, positivism is solely adopted in the quantitative approach, whereas the three remaining
