Back-to-back stem plot of word length?
Writing Selection 1 (from The Three Little Pigs)
The little pig makes a good house
It has a red roof
He is pleased with it
I can play in this house he says
The big bad wolf cannot get me
"Not I", said the pig.

Writing Selection 2 (from a year 10 textbook)
A train makes only two stops after its starting point
At the first stop, one third of the passengers get off and twenty new passengers get on
At the second stop the remaining sixty passengers get off
How many passengers were there originally?
How do I create the stem plot?

the back-to-back stem plot compares the distribution of two data sets, one one the left and one on the right of the middle line. You need to first prepare a frequency table of word lengths for each of the texts, follow the instruction of the following link, which provides examples: http://www.purplemath.com/modules/stemleaf.htm The second example of the following link is a back-to-back stem-and-leaf plot (for two data sets) http://www.purplemath.com/modules/stemleaf2.htm
