Homework Help: Calculate the uncertainty on the values of m

  1. Oct 3, 2011 #1
    1. The problem statement, all variables and given/known data

    m
    7.29
    7.31
    7.3
    7.31
    7.27
    7.28
    7.31
    7.29
    7.28
    7.27
    7.26
    7.3
    87.47
    mean 7.289166667

    using the values in the table calculate the uncertainties on the mean values of m

    3. The attempt at a solution

    I thought finding the difference between the different values of m and the mean value of m, adding them, and dividing by the number of values of m there are, but this doesn't seem right. Please help

    They're probably looking for the Standard Error of the Mean. Take a look at the Examples section http://teacher.pas.rochester.edu/PHY_LABS/AppendixB/AppendixB.html" [Broken].
