What is the meaning of the concept ‘consistency’ in (chemical) measurement?

The range of meanings of the concept ‘consistency’ in daily language is very extensive: think of its use, not only in the measurement context, but also in describing a material property (of concrete, or of tissue of living organisms) or in—of all things—politics (“is a politician consistent in what he says?”). Sometimes, the problem is tackled in the form of questions: is ‘compatibility’ a more “egalitarian” relationship than ‘consistency’? is ‘consistency’ the quality of behaving in the same way? and is being consistent the same as being coherent?
