Answer: D. The interquartile range (IQR) for Town A , 15° is less than the interquartile range for town B , 20°.

Explanation:

The interquartile range is most suitable term to compare the spread of two different data displayed by box-whisker plot.

The formula for interquartile range :-


IQR=Q_3-Q_1

For Town A , First quartile :
Q_1=15

Second quartile :
Q_2=30


IQR=30-15=15

For Town B , First quartile :
Q_1=20

Second quartile :
Q_2=40


IQR=40-20=20

Clearly , the interquartile range (IQR) for Town A , 15° is less than the interquartile range for town B , 20°.
