On most college campuses around the country, one would find it difficult not to run into a coffee cart or a vending machine chock-full of caffeinated beverages. The purpose of this study was to determine whether or not there is a correlation between a student’s academic performance and their daily intake of caffeine. I hypothesized that there would be a negative correlation between these variables. That is, I predicted those who reported low levels of caffeine intake would have higher levels of academic performance. This study consisted of 17 participants who were surveyed over their daily caffeine intake and their academic performance. Once analyzed, the results revealed no support for my hypothesis. Participants who reported high levels of academic performance also reported moderate to high levels of caffeine intake. The positive correlation from the results could be due to students’ tolerance for caffeine. After so many years of drinking the substance on a day to day basis, many could see less of the effects that caffeine has on them.
