We wanted to see if there was a correlation between sleep and/or caffeine and students’ grade point average (GPA). To do this we surveyed 101 Lindenwood undergraduate students. We asked them how much caffeine they consumed in a day, how much sleep they get within a seven day period, and their GPA, as well as basic demographic questions. Our study found that there was a weak negative relationship between sleep and GPA whereas no relationship between caffeine consumption and GPA. We conclude that since no relationship has been found, we have made suggestions on how to investigate further given some of the limitations of our study.
