DataTerminology.comNEW
Data, observations, or analysis presented to support or refute a hypothesis, claim, or decision.
DESCRIPTION
Evidence underpins trustworthy analytics and decision-making. In data work, it includes experimental results, observational data, statistical tests, and model outputs. Strong evidence requires validity, reliability, and relevance to the claim. Epistemic standards guide how evidence justifies beliefs and models. Documentation (model cards, decision logs) records evidence trails for governance and audits. Evidence differs from opinion or anecdote by its demonstrable grounding in data.
