Answer: 7
Step-by-step explanation: The range is the difference between the greatest number in the data set and the least number in the data set.
I would recommend ordering these numbers from least to greatest first.
The data set is already written from least to greatest but I will still list it below.
Least to greatest - 6, 7, 10, 12, 12, 13
Since the greatest number in the data set is 13 and the least number in the data set is 6, we have 13 - 6 or 7.
So the range of this data set is 7.
