Question

What is the difference between the interquartile range of the data set represented by the upper box plot and the interquartile range of the data set represented by the lower box plot?

Answer 1

Answer:

Step-by-step explanation:

InterQuartile Range is the difference in 3rd Quartile and 1st Quartile.

In box-plots, you can see two tails and a box. The left side of the box is the "first quartile" and the right edge of the box is "third quartile".

For TOP BOX PLOT:

3rd Quartile = 41

1st Quartile = 24

So, IQR (interquartile range) = 41 - 24 = 17

For BOTTOM BOX PLOT:

3rd Quartile = 35

1st Quartile = 28

IQR = 35 - 28 = 7

Difference in two IQRs is:

17 - 7 = 10

Correct answer is A
