Sentences with phrase «measurement uncertainty»
Measurement uncertainty refers to the degree of doubt or lack of certainty associated with a measurement. It acknowledges that every measurement we take has some level of inaccuracy or variability, and it provides a range that the true value likely falls within. In simple terms, it means that when we measure something, we can't be completely sure of the exact result, and there is always some level of uncertainty involved. Full definition
The difference can be measured in the models, but it would probably be much less than measurement uncertainty in the real world.
