Conclusions
• Whether or not the student earned AP Stat credit had no relationship on GPA (neither positive, nor negative)
• Early in student’s career, SAT Math score has strongest relationship to GPA
• The relationship between SAT Math score and GPA declines as students progress through university
• The relationship between AP Calc credit and GPA declines as students progress through university
• The relationship between gender and GPA increases as students progress through university
• Quantitative majors (ACCT, FINC, or OPIM) on average have higher Cum GPAs
• These factors account for 25% - 35% of the variation in GPA
