Creating a stem-and-leaf plot in Excel can seem daunting, but it’s actually quite simple once you get the hang of it! These plots are great for displaying data in a way that retains the original values while also showing their distribution. Whether you’re a student trying to visualize your homework data or a professional looking to present your findings, this guide will take you through five easy steps to create a stem-and-leaf plot in Excel.
What is a Stem-and-Leaf Plot? 🌱
Before we dive into the steps, let’s clarify what a stem-and-leaf plot is. Essentially, it’s a method of displaying quantitative data in a graphical format, similar to a histogram, while keeping the original data values intact.
For example, if you have the following numbers: 12, 13, 22, and 23, the stem-and-leaf plot would show:
Stem | Leaf
1 | 2 3
2 | 2 3
In this plot, the "stem" is the leading digit(s), and the "leaf" is the trailing digit.
Step 1: Organize Your Data
The first step to creating a stem-and-leaf plot is to organize your data in Excel. Input your numerical data into a single column, ensuring that each number is placed in its own cell.
Example Data Table
A |
---|
12 |
13 |
22 |
23 |
15 |
18 |

Step 2: Identify the Stems and Leaves
Once your data is organized, you'll need to separate the data into stems and leaves. The stem is generally the first digit(s), while the leaf is the last digit. For instance, in the number 23, the stem is 2, and the leaf is 3.
To do this, you can create two new columns next to your data:
A | B | C |
---|---|---|
12 | 1 | 2 |
13 | 1 | 3 |
22 | 2 | 2 |
23 | 2 | 3 |
15 | 1 | 5 |
18 | 1 | 8 |
In column B, extract the stems, and in column C, extract the leaves.
How to Extract Stems and Leaves:
- Stems: Use the formula =INT(A1/10) for two-digit numbers to get the stem in column B.
- Leaves: Use the formula =MOD(A1,10) to get the leaf in column C.
Step 3: Sort the Data
Now that you have your stems and leaves, sort the stems and leaves to ensure that they are in order. You can do this by highlighting both columns B and C, and then clicking on the "Sort" feature under the "Data" tab in Excel.

Step 4: Create the Plot
Next, you will compile the data into a final stem-and-leaf plot format. You can do this manually in Excel. Here’s how:
- List unique stems in one column.
- Next to each stem, list the corresponding leaves in the same row.
Stem | Leaf |
---|---|
1 | 2 3 5 8 |
2 | 2 3 |
Example of Manual Creation
- For the stem "1", the leaves are "2", "3", "5", and "8".
- For the stem "2", the leaves are "2" and "3".
By aggregating the leaves next to their respective stems, you create your stem-and-leaf plot.
Step 5: Format the Plot for Presentation
Finally, it’s time to format your stem-and-leaf plot for better presentation. You can adjust font sizes, colors, and styles as per your requirements. Here are some tips to make your plot visually appealing:
- Bold the stem values to differentiate them from leaves.
- Align text center for better readability.
- Use borders to separate the data clearly.
