The pie charts illustrate the size of classes in four states in Australia, namely New South Wales, South Australia, Australian Capital Territory, and Western Australia in 2010. Classes were primary.
Overall, it is clear that the category of 21 to 25 students were the highest among other categories regardless of states. However, the reverse was true for classes of more than 30 pupils.
In turn, the highest trends in charts had almost similar patterns as charts with more than 30 students. 21 to 25 student proportions were 37%, 33%, 51%, and 42% respectively. And for group with more than 30 student(4, 4, 7, 5 percentages respectively).
On the other hand, other categories such as 20 students or less and 26 to 30 students were similar with the exception of Australian Capital Territory, state 20 students or fewer followed at approximately the same patterns with 27%, 35%, 38%, 26% respectively. Lastly, 26 to 30 students were not the highest but not the lowest as well, with data 32%, 28%, 10%, and 12% for each state of Australia.
