Design a comprehensive mixed-methods research study to address a significant question in your field of interest. Your proposal should include: 1) a clearly defined research question and theoretical framework; 2) a rationale for employing mixed methods rather than a single approach; 3) detailed sampling strategies for both quantitative and qualitative components; 4) specific data collection methods with justification for each; 5) an analysis plan that addresses how quantitative and qualitative data will be integrated; 6) ethical considerations and limitations; and 7) potential contributions to existing knowledge. Your design should demonstrate innovation in it by either adapting existing methods in novel ways, combining approaches that are not typically integrated, or developing new methodological approaches to address the specific challenges of your research question.
