Stem-and-Leaf Plot

Your stem-and-leaf plot will appear here after you click "Generate Plot".

How It Works

A stem-and-leaf plot splits numbers into a stem (e.g., tens digit) and leaf (e.g., units digit). For example, 23 becomes 2 | 3 when using tens as the stem unit.

Helpful for:

Small to medium-sized datasets
Quickly identifying spread, shape, and mode
Teaching students about data visualization

Help & Tutorial

What is a stem-and-leaf plot?

A simple way to display quantitative data that shows the shape of distribution while preserving the original data values.

How are stems and leaves determined?

It depends on the stem unit you select. For tens, the stem is the tens digit and the leaf is the units digit.

What is it used for?

It's useful for small datasets to quickly visualize distribution, identify outliers, and see the shape of the data.

Example 1: Test Scores

78, 82, 85, 86, 86, 87, 88, 90, 91, 92, 93, 93, 95

Example 2: Ages

12, 13, 14, 15, 16, 21, 22, 23, 24, 31, 32, 35

Example 3: Small Numbers

1.2, 1.3, 1.4, 1.5, 1.6, 2.1, 2.2, 2.3

Use "Tenths" as stem unit
