The chart presents data on the number of students at a UK university who completed their dissertations (either on time or late), failed to submit, or opted to rewrite their dissertations during the years 1990, 2000, and 2010.
It is evident that the completion rates for dissertations, both on time and late, increased significantly over the examined years, whereas the failure rates remained relatively stable, and rewriting occurrences exhibited a varying trend.
In 1990, a total of 100 students completed their dissertations on time, which rose to 150 by 2000, and further escalated to 300 in 2010. Similarly, the number of late submissions experienced an upward trajectory, growing from 30 in 1990 to 50 in 2000, before reaching 75 in 2010. This indicates a marked increase in the overall completion rates among students over the two decades, highlighting a progressive improvement in dissertation management and submission practices.
Contrarily, the number of students who failed to write their dissertations remained steady at 20 between 1990 and 2000, with a slight increase to 30 by 2010. Additionally, students who chose to rewrite their dissertations exhibited varied outcomes: starting with 10 in 1990, this figure rose to 30 in 2000, before declining to 25 in 2010. This fluctuation suggests that while initial rewriting efforts were more prevalent, there was a notable decrease in such instances in the following decade, potentially indicating an improvement in the completion rates and quality of submitted dissertations.
