Uncertainty and the mean and standard deviation

  1. Jul 29, 2009 #1
    I am an independent researcher ready to compile data from an experiment. I have a set of measurements that include the uncertainties of measurement. If I calculate the mean for the set (and thus the standard deviation) do I need to include the uncertainties when doing this calculation?

    No, you do not want to include the measurement errors, as long as these are random errors.

    Why not?
