I do not really know what you are trying to establish. Perhaps the answer is 'The degree of accuracy'. Hope that helps.
accuracy; reliability.
The accuracy of a measurement does not depend on the weight being measured. Instead, accuracy is a measure of how close a measured value is to the true or expected value. To determine the accuracy of a measurement in pounds, you would need to compare the measured weight of 20570 pounds to the actual weight or reference standard.
accuracy refers to how close a measurement is to the true or actual value. precision is a measure of the exactness of a measurement. so if playing darts high precision is like reproduicibility. you can get them all in the same spot. high accuracy would be scattered around the bullseye. if both then it would be close together near the bullseye.
The term for an instrument whose output is consistently higher or lower than the expected value is "bias." Bias occurs when the measurement consistently deviates from the true value in a specific direction.
Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference. The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100. % error = (|Your Result - Accepted Value| / Accepted Value) x 100
Approximation
The closeness of a measurement to the true value is referred to as accuracy. It indicates how well a measured value reflects the actual or accepted true value of the quantity being measured. High accuracy means the measurement is very close to the true value, while low accuracy suggests a significant deviation. Achieving accuracy often requires precise instruments and careful measurement techniques.
accuracy; reliability.
The closeness of a measurement to the actual value being measured is defined as accuracy. Accuracy reflects how well a measurement aligns with the true value, indicating the degree of correctness in the measurement process. Higher accuracy means that the measured value is very close to the actual or true value. In contrast, precision refers to the consistency of repeated measurements, which may not necessarily be accurate.
The closeness to the actual value is called the accuracy. The reproducibility of the measurement is call the precision.
The term that refers to the exactness of a measurement is "accuracy." Accuracy indicates how close a measured value is to the true or accepted value. Additionally, "precision" is often used to describe the consistency of repeated measurements, but it does not necessarily imply closeness to the true value.
Accuracy is the level of closeness between a measured quantity and the actual or standard value. It indicates how well a measurement represents the true value of the quantity being measured.
It's signature figures
In a scientific measurement, accuracy refers to the closeness of your measurement to the 'true value'. The true value is the result to which a large number of independent experiments, carefully conducted, tends.
Accuracy.
If your question is in economics, try there. If your desired True Value is in measurements, then ASTM and similar folk have useful definitions. The True Value of a measurement is the value to which many individual measurements taken by different methods and different experimenters tend. They go on to define Repeatability as the closeness of repeated measurements using the same apparatus etc. And the Reproducibility is the closeness of results achieved by different measurements with different apparatus.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
