Me and some colleagues discussed accuracy of measurements. We didn't agree on how to treat the accuracy if two values are used to find the value, i.e. the difference between two values.
Situation (explanation)
The weight of a mass m of approximately 5 μg is to be scaled. The scale has an error e. How would you treat the error in this measurement if the scaling is done as such. 1 m is scaled in a ≈2 g container. 2 the ≈2g is scaled without m. 3 the difference is between measurements 1 and 2 is used to find m.
What is the error in this measurement?
Cheers!
