Using Scientific Measurements

Using Scientific Measurements

Using Scientific Measurements. 2.3. Accuracy vs. Precision. Accuracy – the closeness of a measurement to the correct or accepted value of quantity measured. Precision – the closeness of a set of measurements of the same quantity made in the same way 4 darts clustered together = acc or pre?.
