Abstract:

Monte Carlo investigations of Bruceton tests twenty-five and fifty trials show the following characteristics 1 a bias in the estimate of the standard deviation causes predictions of reliability or safety based on such tests to be too optimistic 2 there are additional biases in the parameters G and H which will cause underestimates of the errors of the mean and standard deviation 3 there is little correlation between the actual standard deviation and its estimate as obtained from the short Bruceton test 4 the order in which the items of the sample are tested has a serious effect upon the estimates obtained 5 a poor choice of starting level can give misleading results when the step is small.
