How to Use This Calculator
  1. Enter the feature values or paste summary statistics (min, max, mean, std).
  2. Select the scaling method: standardization (Z-score), min-max normalization, or robust scaling.
  3. Review scaled feature range and distribution.
  4. Use standardization for distance-based algorithms (KNN, SVM) and min-max for neural networks.
  5. Always fit scaling parameters on training data only -- transform test data using training parameters.

What each input means

Raw Value
The original unscaled feature value you want to transform.
Minimum Value
The minimum observed value in your feature column.
Maximum Value
The maximum observed value in your feature column.
Mean
The arithmetic mean (average) of your feature column.
Standard Deviation
The standard deviation of your feature column. Used for z-score standardization.

What each result means

Min-Max Scaled Value
Value scaled to [0, 1] range using (x - min) / (max - min).
Z-Score (Standard Scaled)
Number of standard deviations from the mean: (x - mean) / std.
Robust Scaled Value
Scaled using range instead of std dev, less sensitive to outliers.
Max-Abs Normalized
Value divided by the maximum absolute value in the range.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Raw Value = 50, Minimum Value = 0, Maximum Value = 100, Mean = 50 = 5 input(s) provided
  2. Calculate Min-Max Scaled Value
    Min-Max Scaled Value
    0.5 = 0.5
  3. Calculate Z-Score
    Z-Score
    0 = 0
  4. Calculate Robust Scaled Value
    Robust Scaled Value
    0 = 0
  5. Calculate Max-Abs Normalized
    Max-Abs Normalized
    0.5 = 0.5
