Question from Renee: I am an AP Statistics student who is reviewing for the exam. On one of my review worksheets, we have to create a stem-and-leaf plot for values with 2 decimal places (i.e. 9.14, 8.14, 8.74, 8.77, 9.26, 8.1, 6.13, 3.1, 9.13, 7.26, and 4.74). How would I make the stem-and-leaf plot for this? I've already searched your database and nothing popped up. If you could help me, that would be great. Thank you! |
Hi Renee,
This is an unusual data set to illustrate with a stem-and-leaf plot. You could put 9.2 on the stem with 6 as a leaf, 9.1 on the stem with 3 and 4 as leaves, but then I would want 9.0 on the stem wit no leaves. 8.9 on the stem with no leaves and so on to 3.1 with 0 as the leaf. This would make a very long stem with few leaves. It makes me think of Charlie Brown's Christmas tree.
I think a better option is for the stem to be 9., 8., 7., to 3. and the leaves to be 2 digits long. You need some way to separate the leaves. I did so by putting boxes around them. The start of my stem-and-leaf plot is below.
I hope this helps, I really don't know what is expected,
Good luck on the exam,
Penny
