Introduction
The purpose of this research is to explore the relationship between hours of physical activity and level of academic performance among college students. Understanding this association is crucial because physical activity has been linked to various cognitive and mental health benefits, which may influence students’ academic success. The importance of the study lies in providing empirical evidence to support the integration of physical activity programs into college curricula to enhance student achievement and well-being.
The research question seeks to determine whether there is a significant correlation between the amount of time students dedicate to physical activity and their GPA scores. This insight could inform campus health initiatives and academic support services, creating environment-specific strategies to foster better cognitive function and academic performance among students.
Null and Research Hypotheses
The null hypothesis (H0) posits that there is no statistically significant relationship between physical activity levels and academic performance among college students. Formally, H0: There is no correlation between hours spent on physical activity and GPA. The alternative hypothesis (H1) suggests that a
significant relationship exists, i.e., increased physical activity is associated with higher GPA scores. Mathematically, H1: There is a positive correlation between physical activity hours and GPA.
Participants and Sampling Method
The study will employ a stratified random sampling method to ensure diverse representation across different colleges and majors within a large university. The target population is undergraduate students enrolled full-time, with an estimated sample size of 300 participants, which was determined based on power analysis to detect a medium effect size at an alpha level of 0.05. The sample will include students from various demographic backgrounds, ensuring its representativeness of the university’s undergraduate population. Recruitment will be conducted through university email lists and campus flyers, aiming for a representative subset reflecting the broader student body.
Data Analysis
The analysis will utilize Pearson correlation regression to examine the relationship between the independent variable (IV), which is hours of physical activity per week (measured continuously), and the dependent variable (DV), GPA (measured on a 4.0 scale). Both variables are at the ratio level, allowing for parametric testing. The alpha level for significance testing will be set at 0.05. Additionally, a linear regression analysis may be performed to determine the strength of the predictive relationship between physical activity and GPA while controlling for potentially confounding variables such as age and gender.
Results and Discussion
Based on the simulated data, the analysis revealed a correlation coefficient (r) of 0.30 between physical activity and GPA, with a p-value of 0.02. Since the p-value (0.02) is less than the alpha level (0.05), the null hypothesis is rejected, indicating that a statistically significant positive relationship exists between physical activity and academic performance. This suggests that students who engage in more physical activity tend to achieve higher GPAs.
These findings support previous research indicating the cognitive benefits of regular exercise, which may enhance concentration, memory, and overall academic performance. Limitations of this study include the self-reported nature of physical activity data and potential confounding factors not controlled in the analysis. Future research should employ objective measures of physical activity, such as activity trackers, and consider longitudinal designs to better establish causality.
In conclusion, the study provides evidence that promoting physical activity among college students could positively influence academic success. Universities should consider implementing or expanding physical activity programs as part of holistic student support services to boost academic achievement and mental health.
