The pie charts illustrate the class size of primary schools in four different Australian states in 2010.
From an overall perspective, it is readily apparent that classes having 21-25 students was the lagrest share in all four states surveyed, except for South Australia. However, the total number of classes with 30 students or more were lower than those of remainning classes.
As can be seen, the number of classes had 21-25 students was 37% in New South Wales. It was followed by that of those with 26-30 students and fewer than 20 students at 33% and 26% respectively. In South Australia, meanwhile, the percentages of classes comprising under 31 students ranged from 28% to 36%, with classes having a maximum of 20 students being the most popular. Notably, the figures for the biggest class size in both states were the same, each standing at only 4%
Turing to Australia Capital Territory, primary schools attributed to the highest percentage of classes with 21-25 students at 51%. In addition, the level of classes with under 20 students was the highest among the four states with 38%. However, the class size of more than 30 students shared the lowest propotion at 1%. In Western Australia, the percentage of class with 21-25 students was 9% lower than the class in Australia Capital Territory. Standing at 27% the classes containing 26-30 students was almost two time as much as that in Australia Capital Territory. The classes consisted of under 20 students was similar to New South Wales. Finally, the classes with a minimum of 30 students is just 5% in Western Australia, which was five times higher than in the Australia Capital Territory.
