<p>Accuracy vs. Precision</p><p>Accuracy and precision are used in context of measurement. Accuracy is the degree of conformity of a measured or calculated quantity to its actual (true) value, while precision is the degree to which further measurements or calculations show the same or similar results. In other words, the precision of an experiment/object/value is a measure of the reliability of the experiment, or how reproducible the experiment is. The accuracy of an experiment/object/value is a measure of how closely the experimental results agree with a true or accepted value. Both accuracy and precision are terms used in the fields of science, engineering and statistics.
