I could listen to you say uncertainty all day its so satisfying 😂. Also would you be able to make a video on tips for aqa paper 3 on section a? Thank you, your videos have been an extremely useful resource.

Great video, keep it up! Just wondering when you mentioned the absolutely uncertainty in the gradient being the difference between the best and worst gradient, does this always work? I saw another video stating it’s the difference divided by 2 so now I’m a bit confused.

You see when you are trying to find absolute uncertainty from ln table I saw your method in 2019 paper 3 ocr . E.g where you do ln 340 - ln 260 divided by 2. Basically half the range. Does this method work if the table was log(lg)values instead of ln? I think this question could come in paper 3 2022.

you know how there is 2 lines of worst fit which one do i use when finding the uncertainties.
