Homework Help: Fractional uncertainties (Data analysis)

  1. Mar 18, 2009 #1
    I've been trying to determine the Boltzmann constant by observation of Brownian motion. I undertook four experiments and hence got four different estimated values for kB. To analyse the data, I estimated the mean value and the standard deviation. This is maybe not the best way to analyze the data since there are so few data points. I've heard of a method called "fractional uncertainties", but I was unable to find anything relevant by googling.

    What does the method consist of, and should I use it?
