Stem and Leaf Plot Calculator
Generate stem-and-leaf plots and analyze data distribution with statistical insights
Data Input
Enter integers only. Maximum 50 values supported.
Stem-and-Leaf Plot
Stem | | | Leaves |
---|---|---|
0 | | | 69 |
1 | | | 35 |
2 | | | 255 |
3 | | | 47 |
4 | | | 2 |
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.
Statistical Summary
Data Distribution Insights
• The stem-and-leaf plot shows 5 different stems (ten-digit groups)
• Data ranges from 6 to 42
• The median value 23.5 represents the middle of the dataset
• The mode 25 appears most frequently in the data
Sorted Data Values
Data automatically sorted in ascending order for analysis
How to Create a Stem-and-Leaf Plot
Identify Stems
Divide each number by 10, the integer part is the stem
Find Leaves
The remainder when dividing by 10 is the leaf
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
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
