A researcher who wants to use a mixed strategy of inquiry has the assumption that this is the most comprehensive research method. According to Onwuegbuzie & Leech, this strategy of inquiry is not always appropriate for all types of research (2005). The type of research question will determine if using mixed method will be appropriate and useful. Using mixed methods strategy of inquiry can be quite challenging for a researcher, as it requires familiarity in both qualitative and quantitative study and also combining the two methods appropriately is not easy (Onwuegbuzie & Leech, 2005).
In a mixed methods strategy of inquiry, a researcher should ask questions that will gather objective, subjective and intersubjective data. Since mixed methods combine both qualitative and quantitative methods, it has to attain results from both methods. Objective questions will gather data that quantifies measurable data in order to understand a phenomenon. Subjective questions will gather data from individual constructs and interpretation that is not quantifiable. Intersubjective questions will gather data based on the interaction between the researcher and participant of which is subject to bias (Wilson, 2010).
More researchers are using mixed methods strategy of inquiry as it allows a researcher to broaden or narrow down focus as needed in order to concentrate more on data to understand the meaning more. Also, the method is more flexible as words and subjective data can add more meaning to the quantitative data obtained. In psychology, the mixed methods strategy of inquiry can be used to obtain both objective and subjective, and deductive and inductive data that allows psychologist reach a more creative approach in a specific area of study. It also enables triangulation of the two research methods to bring together the pieces of data and come up with a more solid study (Cresswell, 2003).
