The pie chart compares the proportions of four various sections at the National University over a period of three years.
Overall, it is clear that the proportion of computer science increased, however the ratio for business dropped between 1990 and 2010. By contrast, it is interesting to note that the percentages of medicine as well as law fluctuated over the same period shown.
Looking at the pie chart in more detail, level of computer science stood at 30% in 1990, and this figure rose from 40% in 2000 to 45% in 2010, a rise of 5%. Moreover, there was the same degree in the proportion of law in 2010 as well as 1990, 15% respectively.
It could be explained by the fact that the level of medicine remained stable in different two years, which was 25% in both 1990 and 2010, while this percentage went up by 5%, reached 30% in 2000. Interestingly, the same situation observed in the rate for law, which was 15% in both 1990 and 2010, but fell by 5% to reach 10% in 2000.
In conclusion, it can be seen that the both proportions of computer science and business were the same degree at the beginning, while computer science had the highest proportion in the final year.
