The given chart depicts the number of pupils in classes from different countries at two seperate ages.
Overall, the number of students at different ages appears not to differ much in the same country. While some countries may have high number of students per class in both ages, some may not be alike.
A closer inspection into the graph, it can be seen that Russia has the least number of students per class in both ages at just aboce 10 pupils a class. Hong Kong, along with Japan, on the other hand has approximately 35 students at the age of nine in the former, and thirteen in the latter. Besides, staying in the lead, Japan has just above 30 students aged nine, while Hong Kong has quite the same number but for pupils aged thirteen. A similar relationship is mirrored by the United Stated and the Global average, albeit at a lower proportion, amounting for roughly 20 students per class for both ages in both types.
Additionally, the difference between the number of students of different ages in the same country may differ. The number of students in Russia are almost identical in both ages, as opposed to other countries, where there is roughly 10-student difference.
