Answer:
The third box plot.
Step-by-step explanation:
On a box plot, the interquartile range, or IQR, is the "size" of the box, or the distance between the left side (which represents the first quarter) and the right side (which represents the third quarter.)
This is because the IQR is defined to be the difference between the third quarter and the first quarter, or IQR = Q3 - Q1.
As can be seen from the plots given, the third box's distance between the left and right side of the box is the largest. Therefore, its IQR is also the largest.
