Answer:
So, the range of the given data set is 8.
Explanation:
The range of a data set is the difference between the maximum and minimum values in the set. Let's find the maximum and minimum values in the given data set:
Data set: {13, 18, 13, 14, 13, 16, 14, 21, 13}
Maximum value: 21
Minimum value: 13
Now, calculate the range:
Range = Maximum value - Minimum value
Range = 21 - 13
Range = 8
So, the range of the given data set is 8.
