The dot plot provided shows the number of strokes for the ninth hole of a mini-golf course. The goal is to choose the best measure of center (mean or median) based on the data distribution.

### Analysis of the Dot Plot:
- The dot plot appears fairly **symmetrical**, with most strokes clustered around the center (4 to 6 strokes) and fewer data points on the extremes.
- Since the data is **symmetrical** and not significantly skewed, the **mean** and the **median** should be quite close to each other.
  
### Which Measure of Center is Best?
In general:
- **Mean** is best for **symmetric** data because it takes into account all data points and provides a balanced average.
- **Median** is best for **skewed** data because it is less affected by outliers.

Given that the data in this case is nearly **symmetrical**, the **mean** would be the best choice.

### Correct Answer:
- **The mean is the best choice because the data is nearly symmetrical.**

Would you like further clarification or details on how to calculate these measures from the data?

Here are 5 related questions for further exploration:
1. How would the choice between mean and median change if the data were skewed to the right?
2. How can you calculate the mean and median from this dot plot?
3. How do outliers affect the mean in comparison to the median?
4. What are other examples of distributions where the median would be preferred over the mean?
5. What is the significance of using a larger sample size when calculating the mean?

**Tip:** Always check for skewness in the data before deciding whether to use the mean or median as the best measure of center.

A mini-golf course is determining the par score for each of its holes. The dot plot shows the number of strokes required to place a ball in the ninth hole for a sample of 31 players. Which measure of center is best to use to determine the expected number of strokes required for the ninth hole?

Determine the best measure of center (mean or median) for analyzing mini-golf scores. This dot plot shows nearly symmetrical data, making the mean the most accurate measure of the expected number of strokes for the ninth hole. Perfect for students learning about mean and median in Grades 6-8.
