To begin, it's essential to clarify the key variables involved in this study. In this context, the primary independent variable is the education policy under consideration, which could range from changes in curriculum, teaching methods, or even school hours. The dependent variables, or student outcomes, would typically include metrics such as graduation rates, standardized test scores, college enrollment rates, and perhaps more qualitative measures like student satisfaction or engagement levels.
Assumption is the bedrock of causal inference. In this scenario, I would start by assuming that the new policy is the only significant change in the educational environment over the study period. This simplifies the model by focusing on the policy's impact, though in reality, adjustments might be needed to account for other variables that could influence student outcomes....
