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, the percentage of boys in the intermediate level remained static, while girls faced a downward trend.
In 2001, girls and boys who selected science and math at the advanced level accounted for 4% and 3.5%, respectively. In 2007, the percentage of boys studied in the advanced levels dropped significantly by 0.5%, whereas the proportion of girls grew minimally above 4.3%. In 2013, the ratio of students who learned science and math surged marginally to 4.5% for girls, while it dipped sharply for boys to 3%.
Looking at the intermediate level, the proportion of boys remained the same even though it had some fluctuations. Initially, 6% of boys studied science and math at the intermediate level, while after half a decade, it dipped slightly under 6%. Finally, the ratio of boys who learned science and math at the intermediate level reached 6%, as it had at first. In contrast, girls at the intermediate level had a downward trend from 6.5% in 2001 to 4.5% in 2013.
