Quandaries & Queries

Question from Susan, a teacher:

I read your answer to the question about could a box & whisker have NO whiskers.
It made sense to me. However I am preparing for my advanced class and I have a sample graph comparing box plots of data.
Several of the box have only 1 whisker. There is no explanation for this. Can you help me out. I cannot think of a data set that would produce this. Thanks!

Hi Susan,

Try 1, 1, 2, 3, 5. The median is 2, the lower quartile is 1 and the upper quartile is 4.
