How to Normalize Data (Min-Max)

Formula

Normalized = (X - Min) / (Max - Min)

Min-max normalization rescales data to the [0, 1] interval. The minimum maps to 0 and the maximum maps to 1. This is useful when features have different scales and you need them comparable, such as in machine learning preprocessing.

Exemplo Resolvido

Dataset ranges from 20 to 100. Normalize the value 75.

  1. Range = 100 - 20 = 80
  2. Normalized = (75 - 20) / 80 = 55 / 80 = 0.6875
  3. 75 is 68.75% of the way from min to max
