The bar graph illustrates how the status of dissertation done by students in a UK university varied every 10 years from 1990 to 2010.
Overall, the number of essays summited on-time and late rose to varying extents over the given timeframe, while failed dissertations experienced a downward trend and rewritten fluctuated continuously. Notably, students tend to complete their tasks on time throughout the period.
Regarding the increasing states, on-time essays far outperformed all other statuses with around 150 projects initially, before witnessed a surge of its figure to over 350 projects in 2010. This substantial increase exhibited the most significant improvement in student performance, reinforced on-time as the dominant state of dissertation. Similarly but to a lesser extent, delayed dissertations recorded a slight rise, ascending from the lowest point of nearly 25 projects to roughly 50 projects in 2010. Due to this consistent grow, the number of late essays ultimately grew to second place by the end of the period.
Concerning the remaining statuses, the number of failed dissertations was approximately 60 projects in 1990, after which it dropped considerably to the last place with just over 5 projects. In contrast, rewritten essays experienced a more erratic trajectory. Its figure started at just over 5 projects in 1990, thereafter reaching its peak of 40 projects in the middle of the surveyed period then concluded with a modest fall to around 30 projects.
