To find the range of the number of grocery stores, subtract the smallest number from the largest number.
First, identify the smallest and largest numbers from the data:
- Smallest number: 2 (Riverside)
- Largest number: 9 (Watertown)
Now, calculate the range:
Range = Largest number - Smallest number Range = 9 - 2 = 7
So, the range of the numbers is 7.
