Science skills: Measuring results
- The true value of a measurement is the value that would be obtained in an experiment without errors.
- The accuracy of a measurement is how close it is to the true value.
- The precision of a repeated experiment is how close together the measurements are.
- Accuracy and precision are two separate concepts. An accurate measurement is not necessarily precise and vice versa.
- A measurement is repeatable if the results are similar when the experiment is performed again by the same investigator, under the same conditions. This implies the measurements are precise.
- A measurement is reproducible if the results are similar when the experiment is performed again by a different investigator with different equipment. This implies the measurements are accurate.
