In mixed methods research, what is meant by the term "common objective" within multiphase design?

In mixed methods research, particularly in a multiphase design, the term "common objective" refers to the overarching goal that unifies the various studies or components within the research project. This means that, despite using different methodologies (qualitative and quantitative) or phases in the research, all parts are directed towards answering the same primary research question or fulfilling a common purpose.

This shared aim is essential in mixed methods research because it ensures coherence and relevance among the different phases and types of data collected. The integration of qualitative and quantitative approaches should not only coexist but also provide a more comprehensive understanding of the research topic, ultimately supporting the same broader objectives.

In contrast, utilizing a single quantitative method represents a more narrow and less integrated approach, lacking the benefits of drawing on multiple data sources. A focus on statistical analysis alone would miss the rich insights that qualitative data could provide, making it unsuitable for a mixed methods framework. Finally, analyzing only case studies does not encompass the broader quantitative aspect that mixed methods seek to combine, clearly diverging from the concept of a common objective that encompasses diverse methodologies to jointly address a research problem.
