The range is a straightforward measure of the difference between values in a data set. To find the range, we need to subtract the lowest value from the highest value, ignoring the others.
Find the range for the set of data 20, 31, 33, 35, 42, 50, 60, 67.
The range is equal to the absolute difference between the minimum and maximum values.
So, 67 − 20 = 47.
Answer: The range for a given data set is 47.
In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9.
The range for a given data set is 9 - 3 = 6.
Answer: 6
