i need a subheading The proposed study variables are access to afterschool programs (independent variable) and high school graduation rates (dependent variable). The two variables will be studied in a quantitative research study. The (independent variable) conceptualized Participation in organized activities outside of regular school hours, which can involve educational and recreational activities, has an opportunity to influence high school graduation rates. The (dependent variable) conceptualization is the number of students who graduate from high school within the specified period, affected by various factors, including access to after-school programs. This variable will be operationalized by measuring the number of students registered in afterschool programs, how often they go (e.g., how many days a week), and the activities that are offered (for example, academic help, arts, sports, etc.). "This review approach employs quantitative techniques to statistically combine the results from multiple studies, and such systematic reviews of research are at the top of most hierarchies of evidence regarding the effects of social policies and programs (Flay et al., 2005)." l
