The range of a data set is calculated by subtracting the smallest value from the largest value.

Given the data set:
$4, 3, 0, 5, 2, 9, 4, 5$

• The smallest value is $0$.
• The largest value is $9$.

Thus, the range is: $\text{Range} = 9 - 0 = 9$

So, the range is $9$.

2. What is the mean of the given data set?
3. Can you find the median of these values?
4. How would the range change if an additional value, say 10, were added to the data set?
5. What is the variance and standard deviation of the data set?

Tip: The range only considers the extreme values, so it doesn’t reflect any information about the distribution of the other values.
