Data Management: Validity (Definitions)

"A characteristic of the data collected that indicates they are sound and accurate." (Teri Lund & Susan Barksdale, "10 Steps to Successful Strategic Planning", 2006)

"Implies that the test measures what it is supposed to." (Robert McCrie, "Security Operations Management" 2nd Ed., 2006)

"The determination that values in the field are or are not within a set of allowed or valid values. Measured as part of the Data Integrity Fundamentals data quality dimension." (Danette McGilvray, "Executing Data Quality Projects", 2008)

"A data quality dimension that reflects the confirmation of data items to their corresponding value domains, and the extent to which non-confirmation of certain items affects fitness to use. For example, a data item is invalid if it is defined to be integer but contains a non-integer value, linked to a finite set of possible values but contains a value not included in this set, or contains a NULL value where a NULL is not allowed." (G Shankaranarayanan & Adir Even, "Measuring Data Quality in Context", 2009)

"An aspect of data quality consisting in its steadiness despite the natural process of data obsolescence increasing in time." (Juliusz L Kulikowski, "Data Quality Assessment", 2009)

"An inherent quality characteristic that is a measure of the degree of conformance of data to its domain values and business rules." (David C Hay, "Data Model Patterns: A Metadata Map", 2010)

"Validity is a dimension of data quality, defined as the degree to which data conforms to stated rules. As used in the DQAF, validity is differentiated from both accuracy and correctness. Validity is the degree to which data conform to a set of business rules, sometimes expressed as a standard or represented within a defined data domain." (Laura Sebastian-Coleman, "Measuring Data Quality for Ongoing Improvement ", 2012)

"Validity is defined as the extent to which data corresponds to reference tables, lists of values from golden sources documented in metadata, value ranges, etc." (Rajesh Jugulum, "Competing with High Quality Data", 2014)

"the state of consistency between a measurement and the concept that a researcher intended to measure." (Meredith Zozus, "The Data Book: Collection and Management of Research Data", 2017)

[semantic validity:] "The compliance of attribute data to rules regarding consistency and truthfulness of association." (O Sami Saydjari, "Engineering Trustworthy Systems: Get Cybersecurity Design Right the First Time", 2018)

[syntactic validity:] "The compliance of attribute data to format and grammar rules." (O Sami Saydjari, "Engineering Trustworthy Systems: Get Cybersecurity Design Right the First Time", 2018)

"Validity is a data quality dimension that refers to information that doesn’t conform to a specific format or doesn’t follow business rules." (Precisely) [source]
