Measuring Accuracy: Quantitative or Qualitative?

[mahannan]

What is the difference between accuracy of a measurement and its level of accuracy? Is the level of accuracy quantitative or a qualitative measure?

That sounds like two different ways of saying the same thing to me. In science, there are two basic qualities of good measurements, precision and accuracy. Precision is how repeatable the results are. Ie, if they are all clustered around the same value. Accuracy is how far those values are from the actual value for the measurement.
