## 5 Survey Results, Analysis and Discussion
Regarding the impact of MaGraDa on academic performance, the survey results indicated that 65.5% of students believed that using MaGraDa would contribute to achieving better exam grades, while 26.7% of respondents expressed a neutral stance on this matter and only a minority of participants (7.8%) did not perceive MaGraDa as beneficial for improving their academic performance. A statistical summary of the survey variables is provided in Tables 16 and 17. For most items, the mode and median were equal to four, indicating a generally positive assessment. In addition, items D3 (useful for diagnosis and error correction) and D5 (preference for using MaGraDa rather than conventional exercises) stood out with a mode score of five, highlighting a favourable experience with MaGraDa. These findings were aligned with the overall opinions expressed by students, as depicted in Figure 18. Specifically, the data indicated that a small percentage of users (6%) were not satisfied with this software, while a substantial percentage (79.3%) reported overall satisfaction. In addition, 77.6% of students were willing to recommend MaGraDa for learning concepts related to graphs. Although approximately 15% of respondents remained neutral on these matters, it was noteworthy that all of the women answering the survey (100%) expressed overall satisfaction with this software.
