Figure 7
The image depicts a combination bar and line graph showing rating data from one to five stars. The vertical axis on the left represents frequency, ranging from zero to forty, while the horizontal axis displays star ratings from one to five. Each of the five bars corresponds to a star rating, with the height of the bars illustrating the number of respondents for each rating. An orange line graph overlays the bars, indicating the cumulative percentage of responses, ranging from zero to one hundred percent, along the right vertical axis. The line steadily rises, illustrating the increasing proportion of total ratings as the star rating improves.Evaluation of AI tools in higher education, specifically academic writing
