Estimation of measurement uncertainty
Why do we need uncertainty?
One reason is that we need to know the quality of our results and if they are fit for purpose.
The second reason is the interpretation of results: do results diverge or are they indistinguishable?
The third reason concerns the decision-making whether a result is within or outside the specifications.
Only knowledge of measurement uncertainty allows us to make confident decisions in this respect.
Finally, there are scientific reasons:
A
proper measurement uncertainty budget shows that you really understand
your method and gives you indications for method improvement.
So let´s dive deeper into this.
