For this version of the dot plots for both the Junior Varsity and Varsity teams, we will again evaluate the distributions and select appropriate measures of center and spread:

### Analysis of the Dot Plots

#### Junior Varsity Team
- **Distribution Shape**: The data points are spread across the range but cluster more towards the center. This distribution is reasonably symmetric with no obvious outliers.
- **Appropriate Measures**:
  - **Measure of Center**: Both the median and the mean would be suitable, but the mean might better represent the center here due to the symmetry.
  - **Measure of Spread**: Standard deviation is suitable for symmetric distributions without outliers, as it provides a measure of how spread out the values are around the mean.

#### Varsity Team
- **Distribution Shape**: This distribution is also symmetric with a slight clustering around the middle. There are no visible outliers, and the spread is consistent.
- **Appropriate Measures**:
  - **Measure of Center**: Again, both the mean and median could work, but the mean would accurately represent the center for this symmetric distribution.
  - **Measure of Spread**: Standard deviation is appropriate due to the lack of outliers and the symmetric nature of the distribution.

### Conclusion

Here’s how you should assign the measures for this set of dot plots:

- **Junior Varsity Team**:
  - **Measure of Center**: Mean
  - **Measure of Spread**: Standard Deviation

- **Varsity Team**:
  - **Measure of Center**: Mean
  - **Measure of Spread**: Standard Deviation

This approach uses the mean and standard deviation for both teams as the distributions are symmetric and lack outliers, making these measures effective for describing the data.

Would you like more information on how these measures are calculated or used? Here are some additional questions to explore:

1. How is the mean different from the median in terms of calculation and data sensitivity?
2. What factors influence the choice between using standard deviation and interquartile range?
3. How can outliers affect the calculation and interpretation of the mean and standard deviation?
4. What are the implications of using the median and interquartile range in a symmetric distribution?
5. Are there any situations where both

A cross country coach records the number of miles his athletes on the Junior Varsity and Varsity teams ran today and displays the data in dot plots. Given the shape of each distribution, determine which measures of center and spread are appropriate for him to use to summarize the data from each team.
