Answer:
To create an ordered stem-and-leaf diagram for the given data, follow these steps:
1. Separate the data into stems and leaves. The stems represent the tens digit, and the leaves represent the ones digit.
Given data:
20, 5, 13, 17, 5, 9, 21, 10, 13, 14, 27, 15
Stems: 2, 1, 1, 1, 2
Leaves: 0, 5, 3, 7, 5, 9, 1, 3, 4, 7, 5
2. Write the stems in ascending order from left to right.
Stems: 1, 1, 1, 2, 2
3. Write the leaves corresponding to each stem in ascending order.
Stem: 1, Leaves: 0, 1, 3, 3, 4, 5, 7
Stem: 2, Leaves: 0, 1, 5, 7
4. Create a vertical line separating the stems and leaves.
Stem | Leaves
-------------
1 | 0, 1, 3, 3, 4, 5, 7
2 | 0, 1, 5, 7
This is the ordered stem-and-leaf diagram representing the given data.
Please note that the diagram may appear differently depending on the formatting used. In this representation, the stems are listed on the left side, and the leaves are listed on the right side separated by a vertical line.
