The pie chart and bar chart illustrate the proportion of students studying for various amounts of time during their test and their obtained average scores relating to their studying hour.
Overall, it is evident from the pie chart that the highest proportion of students (38%) spent 76-100 hours, while 0-25 hours were spent by the least number of students (5%). The bar graph compares that student’s performance proportionally increased with their studying hours, except for 101-125 hours.
Additionally, 50%, 18%,9% leaners engaged themselves with 76-100 hours, 26-50 hours, and 101-125 hours, respectively.
Furthermore, the bar chart represents that Pupils who studied 76-100 hours for their exam obtained maximum marks, around 95 out of 100, whereas, 0-25 hours learning students hold the least amount of marks, exactly 40. Other groups who learned about 26-50 hours and 51-75 hours acquired just above 60 marks and a little below 80 marks. In contrast, despite studying the highest time period (101-125 hours), these students had an average mark of about 90, which was less than the scores gained by the person who passed 76-100 hours learning period.
