In a box plot ,
the box is drawn from the first quartile to the third quartile and the vertical line inside the box indicates the median.
From the given plot, we get
Lower quartile = 26
Median = 32
Upper quartile = 36
Inter quartile Range (IQR ) = Upper quartile - Lower quartile
IQR = 36 - 26 = 10
Hence, IQR of the given data = 10
