Question

What is the relationship between the accuracy and uncertainty of measurement?

Step-by-Step Solution

Answer

If uncertainty is high in measurements, the accuracy in value is low.

If the measurement is very accurate then the uncertainty is low.

Step 1: Defining a concept of uncertainty and accuracy

Uncertainty is the doubt that exists about the result of a measurement which means how much the values deviate from each other.

Accuracy is how much a measured value is close to the standard value or accepted reference value.

Step 2: Defining relations between the degrees

Accuracy means how close the value of the measurement is. And Uncertainty refers to imperfect or unknown values or information. 

The degree of accuracy and uncertainty are inversely proportional.

If uncertainty is high in measurements, the accuracy in value is low.

If the measurement is very accurate, then the uncertainty is low.
