Frequency Distribution Calculator
Frequency Distribution with explicit assumptions and reproducible inputs.
Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- At most50 user-defined bins. Values outside the edges are reported separately, not silently discarded.
Example Calculation
- Data: 1, 2, 3, 4, 5
- Bin edges: 0, 2, 4, 6
Edges0,2,4,6 group data1,2,3,4,5 into counts1,2,2.
Frequently asked questions
How do I use this calculator?
Enter data, bin edges. The result updates automatically. Use Reset to restore the example values.
What method does it use?
Count observations in [edgeᵢ,edgeᵢ₊₁), including the final right endpoint in the last bin.. At most50 user-defined bins. Values outside the edges are reported separately, not silently discarded.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
