Homework Statement:
The data below is the numbers of dependent children that were recorded in the 50 families' interviews. Arrange the data into an ordered stem and leaf plot.
Relevant Equations:
N/a
The exercise is 2.37 in the book, Exploring Statistics: A modern introduction to data analysis and inference by Larry J. Kitchens 2nd editions.

The data is the following:
3224112341
2012104210
0130322303
2501214305
2011261215

I know the min and the max values are 0 and 6, respectively. But I am having some trouble with the stem and leave part of the plot. I don't know how to represent the data correctly...

I know that this is the right format:

StemLeaves
0
1
2
3
4
5
6



Thanks,

All I know about stem and leaf plots is from a quick search online. Looks like you normally have more digits in the each datum and pick power of 10 exponent at which to separate the stem from the leaf. It's not obvious how to implement that when you only have single digits.
At one extreme, everything is a leaf, so just list all the values in ascending order, showing repeats, in one line. At the other, everything is stem and all the leaves are just zeroes (e.g. if there are three occurrences of 4 in the data then stem 4 has three leaves, all 0.
In between, you would need to create equal sized buckets, like 0-2, 3-5, ... For a datum value n, its bucket would be b(n)=rounddown(n/3)*3 and its leaf would be n-b(n).

If you are expected to solve this question then you should have something in your notes on it.
