Effective Data Analysis

Validity is the degree to which a measure accurately represents or supports conclusions about the construct it is intended to measure.

How it is used
Tests whether a measure represents the intended concept before stakeholders use its results in decisions.
How deep it goes
Defines validity and distinguishes three assessment types, with qualitative guidance for content or face validity.
Examples
Uses job-satisfaction facets, employee well-being measures, and organizational goals translated into specific metrics.
What you can do after
Evaluate/understand whether proposed measures adequately represent their intended concepts and warrant use in stakeholder decisions.

Data Without Labels

Validity is the degree to which data conforms to the properties, characteristics, scope, and variations required by its use case.

How it is used
Uses validity to inspect whether data supports the scope and requirements of a machine-learning use case.
How deep it goes
Defines conformance and gives a scope-based example, but stops short of procedural validation checks or implementation details.
Examples
Uses a 2015–2019 study that incorrectly includes 2014 data to demonstrate invalid scope.
What you can do after
Evaluate whether observations and measurements conform to a use case's defined scope and required characteristics.
