The scatter plot illustrates the relationship between study time and exam scores. It provides evidence that the more time students spend studying, the higher their grades tend to be. We can observe that the scores gradually increase and then level off as study time increases.
Notably, students who prepare for 6 to 10 days achieve very high scores. In contrast, those who study for only two days typically receive scores around 50 to 60. Students who dedicate more than five days to studying generally score between 80 and 100. Undergraduates who study for 3 to 4 days tend to earn scores around 70 to 80, which is not particularly high.
It’s clear that higher scores are associated with more than five days of study. Those who prepare for 6 to 10 days can achieve scores close to 100. Furthermore, it is evident that exam scores depend on the amount of time students spend preparing, with the most effective study period being between 6 to 10 days.
