Find the range of the data set.
To find the range of the data set, we first need to find the highest and lowest numbers in the data set.
The highest number in the data set is 47, and the lowest number is 18.
To find the range, we subtract the lowest number from the highest number:
47 - 18 = 29
Therefore, the range of the data set is 29.
