This report investigates factors influencing the Grade Point Average (GPA) of first-year science students. The analysis includes a comparison of GPA scores between genders using box plots and t-tests, revealing no significant difference between male and female average GPAs. The study also examines the impact of socio-economic status (SES) and parental education levels on GPA, finding that students with undergraduate parents tend to have significantly higher GPA scores. A correlation matrix highlights positive associations between GPA and high school scores in science, English, and math, as well as the Australian Tertiary Admission Rank (ATAR). Regression analysis identifies high school math scores (HS_MATH) as a significant predictor of GPA. Stepwise regression models further explore the relationships between these variables and GPA, with HS_MATH consistently emerging as a key predictor. The final model considers parental education and gender, but these factors do not significantly impact GPA in the presence of HS_MATH. The report concludes that while several factors correlate with GPA, high school math scores are the most reliable predictor of academic performance in the first year of science programs.
