What type of research strategy involves combining both qualitative and quantitative methods?

The choice of mixed as the correct answer highlights a research strategy that effectively integrates both qualitative and quantitative methodologies. This approach is valuable because it allows researchers to leverage the strengths of each type of data.

Qualitative methods often provide in-depth insights into participants' experiences, perceptions, and motivations, which can be crucial in understanding complex phenomena. On the other hand, quantitative methods offer numerical data that can be statistically analyzed, allowing for broader generalizations and the testing of specific hypotheses. By combining these two approaches, mixed methods research creates a more comprehensive understanding of a research question, enabling the researcher to triangulate findings and address them from multiple angles.

This strategy is particularly useful in fields where human behavior and social contexts are important, allowing for richer data interpretation and more nuanced conclusions than either method could provide on its own.
