Justification for Mixed-Methods Approach This research question requires a mixed-methods approach because it aims to measure quantitative outcomes such as changes in BMI, physical activity levels and explore qualitative experiences and perspectives related to program implementation. (Ogden, 2020). Quantitative analysis is needed to statistically assess the effectiveness of the intervention using objective data such as pre- and post-intervention BMI scores, frequency of physical activity, and school lunch consumption patterns. Qualitative analysis is essential for gaining insights into the why and how behind these outcomes understanding lived experiences, attitudes, and the contextual challenges and enablers faced by students, parents, and educators. Together, this approach provides a comprehensive evaluation of both outcomes and processes, improving the ability to refine and scale interventions in similar settings. To support this mixed-methods question, some quantitative data collection strategies that would be appropriate are BMI measurements, which would be collected at the baseline and after the intervention period.
