Without being able to see your image, here are some guidelines:
a) Consider how the key pieces of data on one graph compare to those on the other graph (e.g. compare the mins, lower quartiles, medians, upper quartiles, and maxes).
b) IQR = Q3 - Q1 (ends of the box)
c) Find the difference between the Q2s of each set. (line in centre of each box)
d) Use the numbers you found above to work this out.
The box-and-whisker plot below shows the numbers of text messages received in one day by students in the seventh and eighth grades at Lincoln Middle School.
a) Describe the overlap of the two sets of data.
b) Find the IQR of each set.
c) Find the difference between the medians of the sets.
d) What number multiplied by the IQR equals the difference between the medians of the two sets?
