Since mixed methods research refers to some form of integration of qualitative research methods and quantitative research methods in a single research, it combines at least one qualitative component and at least one quantitative component (Guest & Flemingo, 2015: 582). According to Fischler (n.d), mixed methods research methodology utilizes both quantitative and qualitative data collection methods, for example, interviews and questionnaires, performance tests and observation, etc.
What about mixing investigators of different paradigms to process mixed methods effectively?
definitely, then only it will be a meaningful mixed-method
study
I would careful about how you use the word paradigm. In particular, qualitative and quantitative are not paradigms. Instead, the most commonly used paradigms are post-positivism and constructivism.
This matters because paradigms are philosophical orientations, while qualitative and quantitative refer to methods for collecting and analyzing data. So, while there remain disputes about combining paradigms at the philosophical level, there is little doubt about the possibility of combining qualitative and quantitative methods.
Mathewos W.Giorgis Yes, it is feasible to combine qualitative and quantitative method research to do mixed methods research. The integration of several data collecting and analysis methods in mixed methods research provides for a more thorough grasp of the research subject being researched.
Mixing investigators from various paradigms is also conceivable, although it may be difficult since different researchers may have different viewpoints on study issues, methodologies, and data processing. In order for mixed methods research to be productive, the investigators must share a common understanding of the study issue as well as a shared plan for data collection and analysis. Communication and collaboration among investigators are critical to ensuring that the study is carried out in a consistent and systematic manner.
How else is this supposed to work? The meaningful integration of different perspectives, methodologies and expertises is the most fruitful approach I know of to achieve meaningful research results.
I believe that mixing quantitative and qualitative researchers is not unusual today. More difficult is for a single individual to have skills and knowledge in both methodologies.
