Accuracy and Precision

Accuracy and Precision are both ways to evaluate a set of measurements. They are dissimilar because they are looking at different aspects of the measurements. In the fields of science, engineering and statistics, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity’s true value. ┬áThis article actually focus on statistics to understand “Accuracy and Precision”. The precision of a measurement system, related to reproducibility and repeatability, is the degree to which repeated measurements under unchanged conditions show the same results.
