• In statistics, consistency refers to a property of estimators and estimation.
• In decision theory, a voting system is called "consistent" if and only if it guarantees that whenever option A is the winner both in district 1 and district 2 then option A must also be the winner in the combined district.
• In computer science it is sometimes used to mean data integrity or to refer to a memory consistency model
• Consistency is also occasionally used as a synonym for composition, density or viscosity.
• In sport, consistency refers to a competitor's (or team's) ability to perform to a high standard on a regular basis.
