Carlos is breaking the rule of correlation not equaling causation. Just because individuals in fraternities and sororities have higher GPAs, it does not necessarily mean that their involvement in the Greek system is solely responsible for their academic success. There could be confounding variables at play, such as the individuals who choose to join these organizations being more motivated and academically focused in the first place.
