I'm doing a lab report for a chemistry class, and I need to know how to deal with uncertainties in a particular way. I need to find the mean of the results of three samples, each of which has its own degree of uncertainty. Say that for example I have three samples which returned a result of 100±10, and I need to find the mean of those three samples. Would the mean of that be 100±10, 100±30, something else I can't think of perhaps?
