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.
According to the first chart, students from Finland spent the least time on their assignments, which is 2.8 hours per week, while South Korean students spent 2.9 hours on average, and the Japanese spent 4.3 hours a week. However, Italian learners spent 8.6 hours weekly on their homework, while learners from Ireland and Poland 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 their assignments.
Regarding the second graph, 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, other six nations managed to achieve around 530 marks. However, the United States managed only to get 516 marks, although they spent an average of 6.1 per week on assignments.
