One of the simple ways of determining the uncertainty of a calculated quantity is to use the uncertainty of the measured variables and find the max and min that calculated quantity can be.

In modern laboratory practice, adherence to international standards such as ISO 17025 and ISO 15189 mandates regular validation of analytical methods and the routine estimation of uncertainty.

In this white paper, Sartorius demonstrates how to measure and correct for uncertainty in their Cubis® II laboratory balance using their QApp software.

How do you measure the uncertainty and how to you calculate something with that uncertainty? Before I go on, let me offer this great resource from John Denker - Uncertainty Guide.

What is measurement uncertainty needed for? It enables us to assess the reliability of a measurement, i.e. titration Why does a lab need to know the measurement uncertainty?

But chemists and materials scientists still see AI as a black box. The PNNL data science team's uncertainty measurement provides a way to understand how much they should trust an AI prediction.
