Question

Accuracy is defined as :

• A. A measure of how often an experimental value can be repeated.
• B. The closeness of a measured value to the real value.
• C. The number of significant figures used in a measurement.
• D. None of these

Answer 1

The correct option is B The closeness of a measured value to the real value.

Accuracy is defined as the closeness of the measured value to the real value.

For example : Let say the real value of weight is $10.0kg$.

But the two measured values of weight are $9.8kg$ and $9.4kg$, we say that $9.8kg$ is more accurate value than the other.
