2 The above calculations are the absolute uncertainty of a measurement. The relative uncertainty of a measured value can be determined by dividing the standard deviation by the average value. If you multiply the relative uncertainty by 100, then you obtain the percent standard deviation.

standard or accepted value S of the same quantity. We express the difference between E and S as a percent of the standard value S: 100 S E -S PE = × (1) This formula yields a positive result if the experimental value is high in comparison to the standard value, and a negative result if it is low. A percent difference should be calculated when ...

Accuracy and Precision in Measurements Accuracy is the agreement between an experimental value, or the average of several determinations of the value, with an accepted or theoretical (“true”) value for a quantity. Accuracy is usually expressed as a percent difference: % difference = (experimental – …
