In a study of 200 Division I athletes, variables related to academic performance were examined. A paper reported that the correlation coefficient for college GPA and a measure of academic self-worth was r = 0.46. Also reported were the correlation coefficient for college GPA and high school GPA (r = 0.42) and the correlation coefficient for college GPA and a measure of tendency to procrastinate (r = β0.39). Higher scores on the measure of self-worth indicate higher self-worth, and higher scores on the measure of procrastination indicate a higher tendency to procrastinate. Write a few sentences summarizing what these correlation coefficients tell you about the academic performance of the 200 athletes in the sample. The correlation coefficient for college GPA and academic self worth tells us that among these athletes there was linear relationship between GPA and self worth. Those with higher grades tended to feel those who had lower grades. The correlation coefficient for college GPA and high school GPA tells us that among these athletes there was linear relationship between GPA and high school GPA. Those who had higher grades in high school tended to have those who had lower grades in high school. The correlation coefficient for college GPA and the procrastination measure tells us that there was linear relationship between those variables. Those who had a tendency to procrastinate, generally speaking, had those without that tendency.
