Based on this graph, which student had the greatest individual improvement? The student with the greatest individual improvement was

To determine which student had the greatest individual improvement, we need to look at the difference between each student’s score on the test and their score on the retake.

Based on the graph, here’s the comparison of scores:

1. **Jessica**: Her retake score seems almost the same as her original test score, so no significant improvement.
2. **Bob**: His retake score is higher than his original test score, showing some improvement.
3. **Lydia**: Her retake score is also higher than her original test score, indicating improvement.
4. **Adam**: His retake score is much higher than his test score, showing significant improvement.
5. **Shirley**: Her retake score improved as well, but not as dramatically.

The student with the greatest individual improvement appears to be **Adam**, as his retake score is considerably higher compared to his original test score.

1. How can we calculate the exact improvement of each student using their scores?
2. What is the average improvement across all students?
3. How can we model improvements statistically using mean and variance?
4. How would the result change if we considered percentage improvement instead of raw score improvement?
5. What factors could have contributed to Adam's significant improvement?

**Tip**: When analyzing graphs, it’s helpful to focus on the differences or changes over time rather than just the initial values.
