Sulee explained how to make a box plot to her sister as follows:
“First you find the smallest and largest values and put a mark halfway between
them, and then put a mark halfway between that mark and each end. So, if 10 is
the smallest value and 30 is the largest value, you would put a mark at 20. Then
another mark belongs half way between 20 and 10, which would be at 15. And then
one more mark belongs half way between 20 and 30, which would be at 25. Now, you
put a box around the three middle marks and draw lines from the box to the
smallest and largest values.”
Her box plot is above. What would you say to Sulee?
