The line graph illustrates how many female students studied in four distinct subjects: computer science, physic, medicine, law in one specific university between 1970 and 2015.
Overall, almost all courses witnessed a decrease in the rate of students by varying degrees over the given period, except for the computer science subjects. Notably, law was the most popular course that saw a significant rise in its figure among four surveyed subjects.
The proportion of female students studying law and medicine experienced a similar upward trend in the number of their students. The former initially was the lowest at just approximately 10%, yet it rose dramatically to nearly 90% in 2005, surpassing those three courses. By the end, almost all female students in this university had a law course. Similarly, nearly one-fifth of female students studied medicine in 1970, then it subsequently surged to 70% in 1990, outpacing the share of physic students. The proportion of female medicine students continued to increase gradually to reach its peak at 85% before falling slightly to 80% at the end of the given time frame. Despite that slight decrease, this course still ranked second in terms of student count over the given period.
Turning to the remaining courses, in 1970, computer science was the most popular subject, which had nearly 30% of female students chosen. Then this subject rate rose significantly to 70% in 1990 before experiencing a downward trend to approximately its initial proportion in 2015, ranking the lowest figure. Conversely, the share of physic students witnessed a consistent increase through the given period, from roughly 27% to 77%. Notwithstanding this stable rising, the percentage of this subject stood in the third position, surpassed by law and medicine counterparts.
