Here are the results for Barry Bonds' home runs by year:

### 1. 5-Number Summary
- **Minimum:** 5
- **First Quartile (Q1):** 25.25
- **Median:** 34.0
- **Third Quartile (Q3):** 44.25
- **Maximum:** 73

### 2. Mean, Standard Deviation, and IQR
- **Mean:** 34.64
- **Standard Deviation:** 14.04
- **Interquartile Range (IQR):** 19.0

### 3. Outliers
Using the IQR method, the only outlier is:
- **Outlier:** 73

### 4. Boxplot
The boxplot above visually represents the distribution, with 73 clearly identified as an outlier.

Do you have any questions or would you like further details on any of these calculations?

Here are some related questions to explore:
1. How would the 5-number summary change if the outlier (73) was removed?
2. How do different methods of identifying outliers compare (e.g., Z-score method)?
3. What impact does the outlier have on the mean and standard deviation?
4. How would the distribution change if we added another high outlier, such as 80?
5. How does Barry Bonds' home run distribution compare to other MLB players of his era?

**Tip:** Outliers can significantly affect statistical measures like the mean and standard deviation, so it's essential to consider their impact on data analysis!
