Stem-and-Leaf Plot

Example Data 244 238
The Drupal File ID of the selected dataset. The user may load another using the search bar on the operation's page.


Select one (1) column from a dataset with whole non-negative integers. A good dataset to use would be the Uniform (0,100) dataset. Warning: You may get unexpected results if you use character data or other non-numeric data.


This web application creates a stem-and-leaf plot.

A stem-and-leaf plot is a quick and handy way to visualize the spread of a dataset using only pencil and paper. The idea is to list a column of numbers, usually 0 to 9. These are the "stems". For each value in the dataset, we pair its right-most digit to the corresponding stem that matches it's left digit. For example, if we had a 76 in our dataset, we would pair it with the 7 leaf in the column of numbers from 0 to 9. We then place a 6 as the first "leaf" in that column. We repeat this process for each value in our dataset. In the end, we will get a stem-and-leaf plot like the one seen below.

  0 | 8
  1 | 
  2 | 14
  3 | 4
  4 | 59
  5 | 01
  6 | 3
  7 | 
  8 | 
  9 | 4

The way the app generates the stem-and-leaf plot for your dataset may be different.

The stem-and-leaf plot allows us to see where data may be aggregated.

Use the app above to select a dataset with whole numbers. The app will output the dataset's stem-and-leaf plot once Submit is clicked.
