The graphs show information about how many hours students studied for an exam and what their average scores were.
Overall, students who dedicated a moderate to high amount of time to studying tended to achieve better results, while both very low and high study times were linked to lower average scores.
From the pie chart, we can see that most students studied between 51 to 75 hours. Also 30% of students studied 76 to 100 hours , which is also is a big number. Only 5% studied less than 25 hours , and 9% studied more than 100 hours.
The bar chart shows that students who studied more usually got better scores. The highest scores were for students who studied 76 to 100 hours. But interestingly, students who studied 101 to 125 hours had a little bit lower marks. This shows that too much studying doesn’t always mean better results.
