标 题: how to estimate experimental error?

I saw many papers indicated the uncertainty in graphs. From my opinion, you
have to repeat the experiment several times and know the statistical error.
However, I don't think people have done that for every experiment. So how
did they add the error bar in the graph?
Thanks a lot! | l**l

Otherwise, look at Bayesian data analysis using noninformative prior
distribution if you have time.
