Answer: The range of the data set is: " 16 " .

______

Step-by-step explanation:
The range is calculated by subtracting the lowest value in the given data set from the highest value in the data set.
______

Given: The data set: 9, 21, 7, 11, 13, 21, 5, 14 ;

Let us organize these numbers from lowest value to highest value:
" 5, 7, 9, 11, 13, 14, 21, 21 " ;
Note: This is done by inspection. Note that all eight (8) values are accounted for.
So, we subtract the lowest value in our given data set: "5" ;

from the highest value in our given data set: "21" ; to get the "range":

→ " 21 5 = 16 " ;

______
The range is:
" 16 " .
______
Hope this is helpful! Best wishes!
