Example Data Table

This example uses automatic source bounds with a target range from 0 to 1.

Label	Original Value	Normalized Value
A	12	0.0000
B	18	0.2143
C	25	0.4643
D	31	0.6786
E	40	1.0000

Formula Used

Min max normalization rescales each value from an original interval into a new interval.

normalized = ((x - sourceMin) / (sourceMax - sourceMin)) × (targetMax - targetMin) + targetMin

x is the current value.

sourceMin and sourceMax come from your dataset or custom bounds.

targetMin and targetMax define the final scale.

When sourceMin equals sourceMax, normalization is undefined because the original range width becomes zero.

Frequently Asked Questions

1. What does min max normalization do?

It rescales raw numeric values into a new range, such as 0 to 1 or -1 to 1. This helps compare features measured on different original scales.

2. When should I use automatic source bounds?

Use automatic bounds when your dataset itself should define the minimum and maximum. This is common during exploratory analysis and quick preprocessing tasks.

3. Why would I enter a custom source range?

A custom source range is useful when you already know the valid domain, such as exam scores from 0 to 100 or sensor readings with fixed limits.

4. What happens if values fall outside custom bounds?

Without clipping, outputs can extend beyond the target range. With clipping enabled, those values are constrained to the nearest target boundary.

5. Can I normalize into a negative range?

Yes. You can set any numeric target interval, including negative or reversed ranges, as long as the source minimum and maximum are not equal.

6. Why does the calculator require at least two values?

At least two values are needed to determine a usable range when automatic bounds are selected. A zero-width source range makes normalization undefined.

7. Is min max normalization sensitive to outliers?

Yes. Extreme values can stretch the source range and compress most other results. Consider reviewing outliers before scaling important features.

8. What can I do with the CSV and PDF exports?

CSV export is helpful for spreadsheets, pipelines, and audits. PDF export is useful for reporting, documentation, and sharing results with nontechnical stakeholders.
