From Science Europe Data Glossary
Definition: standardization of data is meant to make data consistent and clear.
Explanation: Consistent is ensuring that the data is reliable so that related data can be identified using common terminology and format. Clear is to ensure that the data can be easily understood by those who are not involved with the data maintenance process. Data can be standardized globally or at a very detailed level. Standardization controls how the terms, phrases, or specific attributes within a data set appear. Statistical standardization and normalization of numerical data are used to make variables comparable by measuring them on the same scale.
