The **range** of a data set is the difference between the highest and lowest values. It is a measure of how spread out the values in a data set are.
To find the range, follow these steps:
Step 1: Identify the highest and lowest values in the data set. Step 2: Subtract the lowest value from the highest value to find the range.
Example 1: Find the range of the numbers 4, 8, 3, 12, 7, 10.
Step 1: The highest value is 12 and the lowest value is 3. Step 2: Subtract 3 from 12: 12 - 3 = 9. Range = 9
Example 2: Find the range of the numbers 15, 22, 30, 10, 18.
Step 1: The highest value is 30 and the lowest value is 10. Step 2: Subtract 10 from 30: 30 - 10 = 20. Range = 20
Find the range of the following numbers:
5, 12, 9, 16, 3, 7
Hint: Subtract the smallest value from the largest value.
