Given :

The data 8, 10, 20, 9, 15, 10, 13, 28

To find :

Range of the data set is

a)28

b) 8

c) 20

d) 0.55

Solution :

Step 1 of 3 :

Write down the given data set

Here the given data set is 8, 10, 20, 9, 15, 10, 13, 28

Step 2 of 3 :

Find maximum value and minimum value

Maximum value = 28

Minimum value = 8

Step 3 of 3 :

Find range of the data set

We know that for a given set of observations range is defined as the difference between maximum value and minimum value of the observations
