Question

define precision and accuracy​

Answer 1

Answer:

• In measurement of a set, accuracy is closeness of the measurements to a specific value, while precision is the closeness of the measurements to each other. More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a true value.

Explanation:

• Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. The best quality scientific observations are both accurate and precise.
