Tom's question suggests that he wants to determine if there is a relationship between studying and class performance, and a positive correlation would indicate that as one variable (studying) increases, so does the other variable (class performance). This would support Tom's hypothesis that spending more time studying will lead to an improvement in his overall class percentage grade.  Negative correlation would indicate an inverse relationship between the variables, zero correlation means no relationship, and nonlinear correlation means that the relationship is not linear and cannot be easily predicted.
