Which of the following is NOT a feature of a mixed-methods approach?

A mixed-methods approach is characterized by its incorporation of both qualitative and quantitative research techniques, allowing for a more comprehensive analysis of research questions. This method emphasizes the integration of diverse data sources, which can provide a fuller understanding of a research topic.

Focusing solely on predefined hypotheses contradicts the essence of mixed methods. This approach often involves the exploration of new or unexpected findings that may emerge from qualitative data, in addition to testing hypotheses. The flexibility to adjust research questions or hypotheses based on qualitative insights is a key advantage of this methodology.

The integration of qualitative and quantitative data enriches the research findings by offering a broader perspective. Additionally, employing multiple sources of data and triangulation enhances the validity of the results, as it allows researchers to cross-verify findings through multiple lenses. Thus, option B stands out as the correct answer because it does not align with the principles of mixed-methods research.
