The box plot below represents some data set. What is the interquartile range (IQR) of the data?
0
20
40
60
80
100
To find the interquartile range (IQR), we need to first identify the first quartile (Q1) and the third quartile (Q3).
Looking at the box plot, we can see that:
- Q1 is approximately 20
- Q3 is approximately 80
Now we can calculate the IQR:
IQR = Q3 - Q1
IQR = 80 - 20
IQR = 60
Therefore, the interquartile range (IQR) of the data set is 60.
