Question

Accuracy refers to

A.) how close a measured number is to zero
B.) how close a measured number is to the calculated value
C.) how close a measured number is to other measured numbers
D.) how close a measured number is to the true value
E.) how close a measured number is to infinity

Answer 1

D.) how close a measured number is to the true value

Explanation:

A measurement is accurate when it is very close to the real value. For example, when the temperature of an object is known and when it is measured, the measurement is close to the already known value. So when we measure something and this property is fulfilled, we can say that we have accuracy in the measurement.
