Hello!
I suppose the title didn't really describe it, but here is the case. I have some data about speed of sound in air which i got by measuring distance and wavelenght (the Kundt's tube experiment).
So now i have three different results for speed which are all in the "Mean value" +- error form. How do i get one mean value and error? How do errors influence the outcome of the result?
There are
v1=324.9+-13 [m/s]
v2=347.76+-13 [m/s]
v3=362.9+-7.24 [m/s]
so I'm looking for vmean+- error.
Any advice is appreciated.
