Percentage error
Leaving Cert Chemistry · Nature of Science
Higher Level
The difference between a measured value and the accepted value, expressed as a percentage of the accepted value. It is found by dividing the error by the accepted value and multiplying by 100, which allows results of very different sizes to be compared fairly.
Ordinary Level
How far a measurement is from the correct value, given as a percentage. A smaller percentage error means a better result.
