Homework Statement
i have a few results of measurements, with different measurement uncertainty: [tex]L=5\pm0,2, L=5,1\pm0,1,L=5,2\pm0,3,L=5,3\pm0,1,L=5,4\pm0,2[/tex] and how can i count standard deviation and final result of measurement with uncertainty?
The Attempt at a Solution
i counted arithmetic mean, variance and standard deviation of all results, if they were the same I would just do this like this [tex]\Delta L=\sqrt{V(L)+U^2(L)}[/tex] where [tex]U(L)[/tex] is measurement uncertainty of a single result, but what to do when they are different?
