Understanding Normalization and Standardization of Data. The term normalization is often thrown around in statistics, business, and data science. In most cases, normalization refers to two different processes: Standardization to a mean of 0 and a standard deviation of 1; Normalization to a minimum of 0 and a maximum of 1 using min-max scaling The formula for Min-Max normalization is Xnorm = (X - Xmin) / (Xmax - Xmin) Where. X is the original data point, Xmin is the minimum value in the dataset, Xmax is the maximum value in the dataset.
