Answer:
80
Step-by-step explanation:
Given in the question a set of number,
15, 21, 57, 43, 11, 39, 56, 83, 77, 11, 64, 91, 18, 37
The range of a set of data is the difference between the highest and lowest values in the set.
To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Step 1
order the set
11 , 11 , 15 , 18 , 21 , 37 , 39 , 43 , 56 , 57 , 64 , 77 , 83 , 91
Step 2
subtraction
91 - 11
80
