Can %age uncertainty in value ever be greater than 100?

[Asad Raza]

We were given an experiment in which the %age uncertainty of majority of students happened to be greater than 100?

Sit in the seat of an off road vehicle and try to draw a graph of a Hooke's Law experiment whilst on the move. How bad could it get?

 

[Asad Raza]

Never did that. You tried it? What was the uncertainty?

 

[sophiecentaur]

I never did it but can't you imagine the sort of results?
If you did the experiment for long enough and took enough readings, you could end up with a pretty good value for the spring constant. Averaging (I.e.data filtering) can be a powerful tool.

Why the uncertainty can not be greater than 100%. Prove it logically?

Why the uncertainty can not be greater than 100%. Prove it logically?

What if the expected result in an experiment is zero? What is the percent uncertainty then?

I don't understand why you are asking the question. You already have data in front of you where the relative uncertainty is greater than 100%, so clearly using that data you can demonstrate that the relative uncertainty can be greater than 100%.

Since you already have data showing that it can be greater than 100%, what is your real question?
