Definition
Accuracy refers to the ability to correctly estimate true value. In surface topography characterization, the accuracy can be interpreted as the capability of an instrument as a whole to predict the true value of a surface topography. The measure of an instrument’s accuracy can be literally indicated using the statistical relation of the measured values with respect to the true value of a calibrated standard.
Scientific Fundamentals
Accuracy Versus Precision
In the fields of engineering, industry, and statistics, the accuracy of a measurement system is the degree of correctness of the measurement in quantity to its true value. The precision of a measurement system, also called repeatability, is the degree to which repeated measurements under unchanged conditions show the same results (Hofer et al. 2005). Although the two words are metaphorical when in use, they are contrary in the context of scientific approach. A...
