    experimental uncertainty (error) and data analysis
    in an experiment to measure the acceleration g due to gravity, two values, 9.96 m/s^2 and 9.72m/s^2, are determined. Find (1) the percent difference of the measurements, (2) the percent error of each measurement, and (3) the percent error of their mean. (accepted value: g= 9.80 m/s^2).

    Percent difference?
    Percent error of E1
    Percent error of E2
    Percent error of mean
