Abstract

Academic performance is a critical determinant of future opportunities, yet the key drivers of GPA variations remain underexplored. This study investigates the factors influencing Grade Point Average (GPA) among university students using statistical methods, including multiple linear regression and correlation analysis. This research aims to identify the most influential factors affecting GPA to provide actionable insights for improving student outcomes. Data for this study were obtained from publicly available datasets on Kaggle, which include variables such as study habits, socioeconomic background, and academic performance. The results indicate that study hours have the most significant positive impact on GPA, while sleep hours exhibit a significant negative correlation. Social hours, physical activity hours and stress levels also show moderate positive effects, whereas extracurricular hours do not significantly affect GPA. The study's limitations include the exclusion of qualitative factors. Future research should incorporate other factors multicollinearity among predictors. Additionally, simplifying the model and using cross-validation could enhance stability and predictive performance.
