The first bar graph illustrates the time spent on homework by 15 year olds in ten different countries in 2015. The second graph highlights the countries with highest marks scored on an international science test by students from the same age group in 2015.
Overall, there appears to be a correlation between two charts where children who spend the least amount of time on homework achieving the highest marks on the science test.
Finnish students spent the least time on their assignments, which is 2.8 hours per week, while South Korean and Japanese students spent 2.9 and 4.3 hours respectively. However, Italian learners spent 8.6 hours weekly, which is the highest. Irish and Polish students spent 7.2 and 6.5 hours per week respectively. Other than that, students from many countries spent around four to five hours per week on average.
The highest marks on the science test were achieved by Finish students with a mean score of 568, regardless the fact that they spent the least time on homework. Aside from Hong Kong, another six nations managed to achieve around 530 marks. However, the United States managed only to get 516 marks which is the lowest. Interestingly, Italians did not manage to enter the top ten.
