A yardstick is rigid - a tape measure is flexible.
It is a unit rate.
Absolute value is a measure of distance.
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.
accuracy; reliability.
No. accuracy is a measure of how close the measurements are to the true value.
Precision
precision
The measurements for all members of the sample are the same.
Earned value management, more commonly known as EVM, is used to measure project performance and advances from a nondiscriminatory perspective. It combines measurements of scope, schedule, and costs.
K-value is a measure of molecular wiight of PVC based on measurements of viscosityof PVC solution.
Approximation
precision and accuracy are defined terms in science.Accuracy is the closeness of a given result to the true value of a measurement. Precision of a result is represented by the scatter of a number of measurements.True value is the average of a number of careful measurements by different experimenters, using different measuring systems. (consider the height of a mountain for example.)Resolution is merely the number of digits in the answer, and of which several may be meaningless.
These two qualities are quite different. First off, the concept of 'true value' should be accepted. This is the value to which a large number of measurements tend. Preferably measurements made by different experimenters and by different methods. 'Accuracy' is the closeness to which an individual measurement approaches the 'true value'. 'Precision' is closely related to resolution. And one may have a very precise answer, but still be well away from the true value. Resolution is the number of digits in the answer - and may well have an illusory value.
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
