The graph delineates the proportion of females engaging in four distinct courses, namely Computer Science, Physics, Medicine and Law. The survey was conducted at one particular university in the period from 1975 to 2015.
Overall, the computer science experienced a fluctuation during the period, with a downward trend from 1990 onwards; while three remaining courses were seen an upward trend. It was also noticeable that the Law suffered a surge in the first 5 years and ended at the first position.
In 1970, the computer science was the most fascinated subject during the pupils, which figure of around 30%. During the period, the figure for this subject rose sharply to nearly 75% before declining gradually to as same as its in 1970. Regarding physics course, the percentage of this subject increased stably, levelling off at around 55% from 1990 to 1995 ,and remaning this upward trend to standing at roughly 80% in 2015.
In terms of medicine course, the proportion of people engaging in this field witnessed a skyrocketing increase by roughly 40% from 1985 to 1990, countining to rose gradually and reaching 90% at the end. This field also surpassed computer science and physics from 1990 to 1995 to finish in the second position. Examining the law field, this course increased rapidly from 1975 onwards, overtaking three remaining courses, before declining in 2010 and immediately recovering to finish in the first-ranked, which figure of nearly 100%.
