A data set has the following values: 5, 7, 8, 12, 14, 18, 21. What is the range of this data set?

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

In this data set:
- The smallest value is \( 5 \),
- The largest value is \( 21 \).

\[
\text{Range} = 21 - 5 = 16
\]

Thus, the range of the data set is **16**.

Would you like more details on this? Here are five related questions to explore further:

1. What is the mean (average) of this data set?
2. How would you calculate the median for this data set?
3. What is the mode, and is there one in this data set?
4. How do you interpret the range in relation to data variability?
5. How does the range compare to other measures of spread like standard deviation?

**Tip:** The range gives you a quick sense of how spread out the data is but doesn’t provide details about the distribution.

Learn how to calculate the range of a data set with values 5, 7, 8, 12, 14, 18, 21. This statistical problem focuses on finding the spread of data by subtracting the smallest value from the largest. Ideal for students in Grades 4-6.
