To find the range of the numbers in the gymnast's data, you need to subtract the smallest number of cartwheels from the largest number.
From the data:
- The largest number of cartwheels is 10 (on Monday and Thursday).
- The smallest number of cartwheels is 3 (on Sunday and Tuesday).
Now calculate the range:
Range = Largest number - Smallest number = 10 - 3 = 7
Therefore, the range of the numbers is 7.
