ABSTRACT
This is also the first chapter in which we will need to delve into derivations and mathematics beyond the basics. The approach taken is to present the minimum needed to grasp the concepts, and you should be prepared to seek out some of the cited materials to complete your understanding. To reiterate a point made earlier, the examples here are strictly that and are not intended to be recipes or critiques. There are many ways to approach uncertainty estimation in weighing and many ways to meet our criterion of reasonable -defensible-fit-for-purpose.
