How to read: Each row shows a stem (tens digit) and its leaves (units digits).

For example: 2 | 5 5 represents the numbers 25 and 25.

How to Create a Stem-and-Leaf Plot

1

Identify Stems

Divide each number by 10, the integer part is the stem

2

Find Leaves

The remainder when dividing by 10 is the leaf

3

Organize

Group leaves with the same stem and sort

Key Features

Shows data distribution clearly

Preserves original data values

Easy to identify median and mode

Handles negative numbers

Shows frequency patterns

Compact data visualization

Understanding Stem-and-Leaf Plots

What is a Stem-and-Leaf Plot?

A stem-and-leaf plot is a data display technique that shows the distribution of quantitative data while preserving the original data values. It's particularly useful for small to medium-sized datasets.

Key Components

  • Stem: The tens digit (or higher) of each number
  • Leaf: The units digit of each number
  • Separator: Usually a vertical line (|) between stem and leaves

Example Interpretation

2 | 5 5 8

This represents the numbers: 25, 25, and 28

Advantages

  • Data Preservation: All original values remain visible
  • Shape Recognition: Easy to see distribution shape
  • Quick Statistics: Median and mode are readily apparent
  • Outlier Detection: Unusual values stand out

Special Cases

Negative Numbers: Stem is negative, leaf is positive

Example: -23 → stem: -2, leaf: 3

Single Digits: Use stem 0 for numbers 0-9

Example: 7 → stem: 0, leaf: 7
