Min-Max Normalization Tool

Scale a numeric dataset to a requested inclusive range.

Description

Scale a numeric dataset to a requested inclusive range.

Min-Max Normalization Tool: Scale a numeric dataset to a requested inclusive range.

When to use Min-Max Normalization

Use this normalization to put numeric features on a defined scale before comparison, visualization, or algorithms sensitive to magnitude.

Values
Required list input.
Target minimum
Optional number input.
Target maximum
Optional number input.

How Min-Max Normalization works

Scale a numeric dataset to a requested inclusive range. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1

Normalized values
The resulting normalized values returned as a list.
Source minimum
The resulting source minimum returned as a number.
Source maximum
The resulting source maximum returned as a number.

Limitations and assumptions

  • Scaling parameters must be learned from the appropriate training or reference population. Constant features, outliers, missing values, leakage, distribution shift, and inverse transformation require explicit policies.
  • Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Alternative or Complementary approaches

Store the fitted parameters, apply them unchanged to later data, inspect distributions, and compare robust scaling when outliers dominate.
