This graphic gives us information about the size of classes in primary schools in four states in Australia the year 2010.
Overall, the amount of the largest classes are situated in New South Wales, the South australia and the Western Australia. However, we see that in Australia Capital Territory the half of the total is occupated by classes with 26-30 students. But we also observe that one third of the classes in Australia Capital Territory are the smallest where the amount of students is lower than 20 students by classe.
We observe on this pie chart, that in three states out of four the percentage of classes with 21-25 students is nearlly identical with 30 percent. We also see that in this same states the propotion of the largest classes is also the same with approximately 5 percent. The quantity of the smallest classes are also the same with just some percent of difference.
However, the last pie chart about the Australia Capital Territory is completely different of other ones. The half of classes in this state contain between 21 to 25 students, but the classes with 30 students and more are inexistant only one percent of all.
