The bar chart illustrates the number of students at a UK university who either completed their dissertation projects on time or late, failed to write them, or had to rewrite them in the years 1990, 2000, and 2010.
Overall, the majority of students completed their dissertations on time in all three years, and this number rose steadily over the period. In contrast, the figures for those who failed to write or had to rewrite their dissertations were consistently low.
In 1990, around 150 students managed to finish their dissertations on time, while the number increased to roughly 230 in 2000 and peaked at about 300 by 2010. This demonstrates a clear upward trend in punctual completion. Conversely, the number of students who completed their dissertations late remained relatively low, fluctuating slightly between about 30 and 50 across the three years.
The figures for students who failed to write their dissertations and those who had to rewrite them were minimal. In 1990, roughly 40 students failed to submit their work, but this number declined noticeably in the following years. Similarly, only a small proportion of students rewrote their dissertations in each period, with the figures remaining below 30 throughout.
In summary, timely dissertation completion became increasingly common among university students over the two decades, while the proportion of those struggling to finish or rewrite their work showed a gradual decline.
