The given line graph depicts the proportion of girls and boys who learned both math and science during intermediate and advanced levels in Australia over a period of 12 years from 2001.
Overall, it is evident that the percentage of girls who chose science and math at the advanced level increased, whereas boys decreased. Moreover, boys in the intermediate level remained static, while girls faced a downward trend.
In 2001, 4% of girls selected science and math at the advanced level, and then it grew minimally above 4% in 2004. After 4 years, nearly 4.4% of girl children joined advanced science and math classes, and in 2011, the proportion of joinees to the advanced levels surged marginally by 0.1% and remained unchanged until 2013. The ratio of boys who joined the intermediate level was constant, even though it had some fluctuations. Initially, 6% of the boys studied math and science at the intermediate level, while after half a decade it dropped slightly below 6%, and then it rose to 6% and remained unchanged.
In contrast, the percentage of advanced boys and intermediate girls who went for science and math accounted for 3.5% and 6.5%, respectively, in 2001. In 2007, boys in the advanced levels dropped significantly by 0.5%, and girls in the intermediate level dipped sharply to 5%. In 2013, the proportion declined dramatically to 3% for the former and 4.5% for the latter.
