Histogram Maker
A histogram turns a messy list of numbers into a clear picture of how your data is spread. Paste your numbers, choose the number of bins, and get an instant chart with stats and a bin table — great for students and quick data checks.
| Bin | Range | Count |
|---|
How to use
- Paste your numbers into the data box — commas, spaces or new lines all work.
- Set the number of bins (fewer bins = wider groups, more bins = finer detail).
- The chart, stats and bin table update as you type.
Good to know
- Fewer bins show the big picture; more bins reveal detail but can look noisy — try 5 to 10 as a starting point.
- Bins are equal-width, and the final bin includes the maximum value.
- Non-numeric entries are skipped, so clean your data first for accurate counts.
Note: Bins are equal-width. The last bin includes the maximum value. Non-numeric entries are ignored and counted for you.
