It seems you're sharing golf scores for a set of golfers with two different designs (possibly for two courses or rounds). Based on the scores provided, we can analyze a few aspects of the data, such as:

1. **Score differences**: Calculate how the golfers' scores changed between the old and new designs.
2. **Average scores**: Compute the average score for both the old and new designs.
3. **Score changes**: Determine if the new design generally led to lower or higher scores on average.
4. **Performance comparison**: Identify which golfers improved or worsened in the new design.
5. **Statistical analysis**: Calculate the variance and standard deviation for both designs to understand score consistency.

Would you like me to calculate any of the above? Here’s a brief example of calculating score differences for each golfer:

| Golfer | Old Design Score | New Design Score | Difference (Old - New) |
|--------|------------------|------------------|------------------------|
| 1      | 81               | 78               | +3                     |
| 2      | 78               | 82               | -4                     |
| 3      | 83               | 78               | +5                     |
| 4      | 80               | 76               | +4                     |
| 5      | 87               | 92               | -5                     |
| 6      | 87               | 83               | +4                     |
| 7      | 89               | 88               | +1                     |
| 8      | 94               | 89               | +5                     |

Would you like more details or further analysis?

### Five Questions:
1. Would you like to know which golfer had the greatest improvement?
2. Are you interested in the average score change for all golfers?
3. Do you want to know the overall trend in performance between the old and new design?
4. Should I calculate the standard deviation of

Golfer	Score (old design)	Score (new design)

1	81	78
2	78	82
3	83	78
4	80	76
5	87	92
6	87	83
7	89	88
8	94	89

Analyze golfer scores from two different designs with statistical methods. Calculate the score differences, averages, and standard deviations to identify trends. Suitable for students learning data analysis and statistics in Grades 7-10.
