The provided chart demonstrates how many students graduated either on time or late, failed to write and rewrote their dissertation projects in a UK university between 1990 and 2010.
Overall, there was a substantial increase in the number of students completing their dissertation on time, while the other categories of late, failure to write and rewriting experienced modest fluctuations
In 1990, the number of students who completed their dissertation was the dominant, standing at around 150, after which witnessed a significant growth to over 200 in 2000 and reached a peak at 300 at the end of the period. Similar changes can be seen in the figures for late completion, which began at about 20, 30 and 40 respectively in the three years, showing a minimal variation.
The number of students who failed to write their dissertation, by contrast, showed a gradual decrease, which was nearly 50, followed by a decrease to a half and hit the lowest point at under 10 in 2010. Meanwhile, the number of students who rewrote was the lowest over the surveyed period. The figures remained at roughly 10 in 1990, after which saw a mild rise to 20 before ending the period at 15.
