I run a calculation to obtain a value P.
In order to get some kind of idea about the uncertainty the calculation, I created 5,000 sets of simulated data and tried to find a value P for each one of them.
The results were that the mean value of P for the 5,000 tests was:
The standard deviation was:
I just want to be sure of the correct way to quote these values.
Should it be:
20.04 +/- 0.70 %
20 +/- 1 %
or maybe something else?
I’ve never quite understood this. Is it a matter of opinion or is there a correct way?
If you could provide reasoning along with the answer that would be great, thank you.
