Bayesian probability theory is employed to derive robust, outlier tolerant methods for the estimation of a quantity and the determination of the uncertainty associated with this estimation given a set of data. The procedure is applied to the estimate of the Newtonian constant of gravitation G yielding G=6.67414(24)X10{-11}m{3}kg{-1}s{-2} This value is in good agreement with the recently published value of the 2002 CODATA adjustment but offers a four-fold reduced, rigorously calculated uncertainty. The uncertainty reflects-unlike results from the conventional least squares analysis-the quoted uncertainties of the data as well as the data scatter.
