How to Make a Stem & Leaf Display

by Michael Cohen

A stem and leaf plot, also known as a stem and leaf display, is a simple, clear method of data organization. Stem and leaf plots highlight the distribution of data across a set, and are particularly useful in sets with large quantities of numbers, such as temperature information or sports scores. Even if you don't have a degree in statistics, you can easily create a stem and leaf display to organize and evaluate your data.

Step 1

Create a chart containing two columns, divided by a vertical line in the center. Add a title to your chart, describing the data that you will present.

Step 2

Label the column on left "Stem" and the column on the right "Leaf."

Step 3

Place the range of "tens" digits represented by your data in the left column of your chart. Only list each digit once. Include all tens digits within the bounds of your data set, even if there are no data points that correspond to that digit. For instance, if your data set consisted of: "22, 26, 40, 54, 59, 77" your left column would read: 2 3 4 5 6 7

Step 4

Place the "ones" digit of each data point in the right column, in the row of the corresponding tens digit. Separate each entry by a single space. For the example data set, your chart would appear: 2 | 2 6 3 | 4 | 0 5 | 4 9 6 | 7 | 7
