About this calculator
Overview
A stem-and-leaf plot is a classic way to display the shape of a distribution. It splits each number into a 'Stem' (leading digits) and a 'Leaf' (trailing digit), providing a textual histogram that preserves the original data points.

Pro Tips
The 'Stem Unit' defines the power of ten for the split. 10 is standard for two-digit numbers.
Look for rows with many leaves—this quickly identifies the mode or clusters in your data.
Gaps in the stems indicate ranges with no data, which might be important outliers.

"It combines the benefits of a raw list and a histogram into a single visualization."
"Stem-and-leaf plots were originally designed for quick manual data organization before the computer era."
