Answer: 6
Explanation:
The range of a data set is the difference between the highest and lowest value. To solve this math problem, we will first find the highest and lowest value in the set.
1. Look at the data set: {12, 10, 10, 8, 6, 7, 7, 12}
2. To find the highest value, look for the largest number. The highest number in the set is 12.
3. To find the lowest value, look for the smallest number. The lowest number in the set is 6.
4. To calculate the range, subtract the lowest value from the highest value. 12 - 6 = 6
5. The range of the data set is 6.
