The pie charts give information regarding the class size of primary schools in four different Australian states in 2010.
From an overall perspective, it is readily apparent that 21-25 students is the most prevalent size in most states, with the exception being South Australia. In addition, it is also worth noting that classes rarely exceed 30 students.
With regard to New south Wales, the proportion of classes within the 20 or lower student range constituted 26%, which was 10% lower than that of South Australia. The percentage of classes containing 21-25 students, on the other hand, represented 37% in New south Wales, whereas South Australia took up only 33%. A similar discrepancy could be seen in the 26-30 student size, where New south Wales was 5% higher than its Southern counterpart. The remaining 4% of both states represented the classes with over 30 students.
As for the Australian Capital Territory and Western Australia, the 21-25 student class size took up the largest percentage, constituting 51% and 42% respectively. Furthermore, one tenth of the classes in Australian Capital territory consisted of 26-30 students, which was 17% lower than Western Australia’s. In terms of the classes with fewer than 20 students, 38% was the proportion in Australia Capital territory, whereas Western Australia had over a quarter of all classes. The statistic relating to classes with a minimum of 30 students is just 5% in Western Australia, which was 5 times higher than in the Australian capital territory.
