Can taking chess lessons and playing chess daily improve memory? An article describes a study in which sixth-grade
students who had not previously played chess participated in a program in which they took chess lessons and played chess daily for 9 months. Each student took a memory test before starting the chess program and again at the end of the 9-month period. Data (read from a graph in the article) and calculated differences are given in accompanying table.

The table shows the memory test scores of the sixth-grade students before and after participating in the chess program:
| Student | Before | After | Difference |
|---------|--------|-------|------------|
| 1 | 70 | 81 | 11 |
| 2 | 68 | 85 | 17 |
| 3 | 75 | 87 | 12 |
| 4 | 78 | 92 | 14 |
| 5 | 80 | 83 | 3 |
| 6 | 72 | 79 | 7 |
To determine whether the chess program improved memory, we can analyze the differences:
- Student 1: Improved by 11 points.
- Student 2: Improved by 17 points.
- Student 3: Improved by 12 points.
- Student 4: Improved by 14 points.
- Student 5: Improved by 3 points.
- Student 6: Improved by 7 points.
From this data, we can observe that all students experienced an improvement in their memory test scores after participating in the chess program. Although the extent of improvement varies between students, the overall trend suggests that the chess lessons and regular practice had a positive impact on memory.
