Data Standardization

Converting data into a consistent format and set of codes, such as ISO dates, country codes, units and naming conventions.

Definition

Standardization enables matching, joining and aggregation across sources. It is distinct from statistical standardization (z-scores) used in ML.

Example

Converting 'USA', 'U.S.', 'United States' to the ISO code 'US'.

Exam tip

Data standardization (formats and codes) is not the same as z-score standardization.
