The provided bar chart illustrates how many dissertations were submitted by postgraduates according to four distinct statuses in a particular UK university every ten years, from 1990 to 2010.
Overall, while the number of completing and rewriting dissertation projects saw a net increase, this figure of those failed to write decreased during the period shown. It is also reported that the vast majority of postgraduates completed their theses on time.
The year 1990 witnessed 150 theses submitted on time. Following that, this figure increased moderately before surging to finish at 300, marking the highest data point of the entire chart. Also undergoing a similar upward trend, but with much lower figures, theses that submitted late experienced its numbers doubling from approximately from 25 to 50 by the end of the period.
In stark contrast, what is more stiking is the number of students failng to write dropped precipitously, from just under 50 to nearly 10, marking the most drastic change throughout the examined time. Finally, the ‘rewrote’ category displayed an inconsistent pattern, as it rose significantly to about 30 and declined steadily to around 20.
