how to find est. uncertainty when given a true mass and an inaccurate mass?

Question

Theoretically, if you know a "true" value of something, but the scale reads differently, the estimated uncertainty of the scale would be the true value minus the scale value, correct?

 

I am given the true mass of an object, but the scale reads something different. I'm asked to determine the estimate uncertainty of the scale, would this be correct?

Answer 1

your suggested answer certainly seems reasonable to me.

perhaps you should express it as a percentage based on ratio of the difference to the true value.
