Consider the data points 25, 3, 17, 12, 22, 34, 12, 11, 16, 42, 9, 12, 17. In this case we will consider the stems to be the tens digits and the leaves to be the ones digits. This gives

Table 1.8.3. Stem and Leaf Plot (unordered)

Stems	Leaves
0	3 9
1	7 2 2 1 6 2 7
2	5 2
3	4
4	2

Then, an ordered Stem and Leaf Plot would be

Table 1.8.4. Stem and Leaf Plot (ordered)

Stems	Leaves
0	3 9
1	1 2 2 2 6 7 7
2	2 5
3	4
4	2

Notice, in each case you can extract the original data values by recombining the stem with a corresponding leaf. Indeed, for these 13 data values the median should be be 7th in the sorted list or the value in the 10’s stem with leaf 6...that is, 16.
