Here is a link to a presentation that I gave for the IoP on AH Uncertainties
Below is attached various useful documents to assist you in this vital part of the course. It is when you begin to use this material when going through your own experiments that it will become clear. Take time to read and understand it.
Use this document very sparingly, it is not compatible with some of the AH mark scheme, especially in that it recommends you always round UP in an uncertainty. This is NOT what you should do at AH.- You’ve been warned! Contact me if you have concerns.
