Given:
The data values are 21, 18, 37, 42, 47, 75, 66.
To find:
The range of the given data set.
Solution:
The data values are
21, 18, 37, 42, 47, 75, 66
Arrange these values in ascending order.
18, 21, 37, 42, 47, 66, 75
Now,
Range = Maximum value - Minimum value
= 75 - 18
= 57
Therefore, the range of given data set is 57.
