Control is inherent in this method of inquiry which is another underlying assumption of quantitative research. Methodological assumptions consist of the assumptions made by the researcher regarding the methods used in the process of qualitative research (Creswell 2003). Statistics can be used to formally test hypotheses or predictions. Journal of Advanced Nursing. ; The qualitative researcher is the primary instrument for data collection and analysis. Nursing Research: Generating and Assessing Evidence for Nursing Practice (9th ed). Post-positivism allows researchers to examine realities through a variety of measurement tools; thus accessing realities which could elude measurement by direct observation (Giddings & Grant, 2007; Schumacher & Greener, 1992). Qualitative approaches allow you to delve deeper into ideas and experiences. The aim of inquiry is to generalize from the particular and apply a theoretical framework that can be applied universally (Hathaway, 1995). The researcher conducting empirical analytical inquiry makes decisions that will reveal what is generally applicable to all similar situations (Firestone, 1987; Smith, AAA; Smith, Bibb). Before assigning numbers there is an assumption that the measurement tool(s) will be accurate in measuring the phenomenon. endobj As a public service, this will now be clarified Assumptions in your study are things that are somewhat out of your control, but if they disappear your study would become irrelevant. Could be quantitative (size, weight, etc.) Survey Research is the most elementary tool for all sorts of quantitative research techniques. Common qualitative methods include interviews with open-ended questions, observations described in words, and literature reviews that explore concepts and theories. Ontologically the researcher assumes that the external reality is comprised of facts that are law-like and provide structure or a theoretical framework to this reality. Researchers using a more moderate approach within the post positivist paradigm recognize that research is a human endeavor. In other words, an assumption is an act of faith which does not have empirical evidenced to support. 0000005874 00000 n

For example, gathering of video evidence, texts or messages for analysis. Attempts to find cause-and-effect correlations between the factors True experiments are fairly like these types of designs, but there are a few crucial differences. Taking a critical stance, Habeas (1971) claimed that such inquiry implies a dissociation of knowledge from human interest (Habeas, 2005) and questions the it with individual contexts, values, and preferences.

The conviction that there is a reality existing outside of the researcher, hat this reality can be observed (ontology), and that knowledge of this reality can be measured objectively (epistemology) are foundational assumptions in quantitative research (Hathaway, 1995).
