The difference between accuracy and precision is both precision and accuracy are two ways of how scientists think about error. However, accuracy refers to or meaning to how close a measurement is to the true or accepted value. On the other hand, precision refers to or meaning to how close measurements of the same item are to each othe But scientists use the best quality of scientific observations and are both accurate and precise.
