Question: Find the interquartile range from the given box-and-whisker plot.



A ) 37.5
B ) 12.5
C ) 25
D ) 50

Steps to derive

1 Interquartile range is the difference between the upper quartile and the lower quartile.

2 From the given box and whisker plot, the upper quartile is 37.5 and the lower quartile is 12.5.

3 Interquartile range = upper quartile - lower quartile
3 = 37.5 - 12.5 = 25

4 So, the interquartile range for the given box and whisker plot is 25.



Hence the right answer is Option C
