How do you know if results are precise?

How do you know if results are precise?

Find the difference (subtract) between the accepted value and the experimental value, then divide by the accepted value. To determine if a value is precise find the average of your data, then subtract each measurement from it. This gives you a table of deviations.

Is percent error a measure of precision?

The percent error is the ratio of the error to the actual value multiplied by 100. The precision of a measurement is a measure of the reproducibility of a set of measurements. The significant figures displayed on an instrument are an indication of the precision of the instrument.

What percent error is too high?

In some cases, the measurement may be so difficult that a 10 % error or even higher may be acceptable. In other cases, a 1 % error may be too high. Most high school and introductory university instructors will accept a 5 % error. But this is only a guideline.

What is the difference between precision and accuracy?

Accuracy refers to how close measurements are to the “true” value, while precision refers to how close measurements are to each other.

What does it mean to be precise but not accurate?

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. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise.
