What is the Interquartile Range of a Data Set?
The interquartile range of a data distribution can be defined as the middle values are spread out in a data. By implication, it means that the interquartile range can help us determine the spread of the data around the central values.
How to Find the Interquartile Range of a Data Set?
Interquartile range = Third quartile - First quartile
Given the data set: 8, 11, 14, 16, 17, 21, 21, 24, 27, 31, 43, 47
The third quartile = 29
The first quartile = 15
Interquartile range of the data = 29 - 15
Interquartile range of the data = 14
In conclusion, the interquartile range helps tell the spread of the data around the central value. The interquartile range, which is 14 feet, represents spread the central values of the heights of the trees.
