The bar chart represents data regarding the progress of dissertations done by students in a UK university in the years 1990, 2000, and 2010.
Overall, all categories recorded growth to varying extents, except for failed submissions, which showed a substantial decline. Notably, the majority of students were likely to submit their dissertations on time.
Looking first at the increasing categories, on-time dissertations led the chart with an impressive number of 150 projects initially, then surged to over 350 by the end of the period, solidifying its top position throughout the chart. A similar pattern was observed in late dissertations, but to a lesser extent. Its figure stood at approximately 25 projects in 1990 before doubling to 50 by 2010. Despite ranked third by 1990, late dissertations finally ascended to second position in the final year.
Turning to the remaining categories, failed dissertations accounted for over 50 projects initially. Its figure dropped gradually to approximately 48 before continuing to decline to its lowest point of about 10 projects in 2010. Rewritten dissertations, on the other hand, showed a more erratic trajectory. Although 1990 witnessed a notably increase from nearly 10 projects to 48 by 2000, its figure significantly dropped by 5% at the end of the period.
