The mean of the data set is approximately 15.07, and the standard deviation is approximately 2.19.

Would you like to go into more detail or have any questions?

Here are five related questions to expand your understanding:

1. How does the standard deviation help in understanding the spread of data?
2. What is the difference between population and sample standard deviation?
3. How does removing an outlier from the data set affect the mean and standard deviation?
4. Can you explain how the mean and median would compare for this data set?
5. What is the relationship between variance and standard deviation?

Tip: A lower standard deviation indicates that the data points tend to be closer to the mean, while a higher value suggests a wider spread.
