1. Accuracy

the quality or state of being correct or precise it called accuracy.

2. Precision

the quality, condition, or fact of being exact and accurate.

3.Error estimationof errors-absolute

theabsolute error is the magnitude of the difference between the exact value and the approximation. The relativeerror is the absolute errordivided by the magnitude of the exact value. The percenterror is the relative errorexpressed in terms of per 100.

4.Relative error

Relative error is a measure of the uncertainty of measurement compared to the size of the measurement. ... Relative error is also known asrelative uncertainty or approximation error.

5. Percent error

Percent error, sometimes referred to as percentage error, is an expression of the difference between a measured value and the known or accepted value. It is often used in science to report the difference between experimental values and expected values.
