Here are 5 related questions for further practice:

1. How would the average change if a new value, 2.5, were added to the table?
2. How can you calculate the median for this dataset?
3. What is the standard deviation of this dataset?
4. How does the range of this dataset compare to its average?
5. What is the difference between calculating a mean and a weighted mean?

Tip: The mean is sensitive to extreme values (outliers), while the median provides a central tendency less influenced by such values.
