Some observations on repeated spring balance weighing designs

Abstract

SummaryDey [3] has suggested a spring balance weighing design in preference to "repeated designs ", and later, Kulshreshtha and Dey [5] have suggested yet one more weighing design which, they say, would be preferred to "repeated designs" and to those suggested in [3], provided one is interested in estimating the weights of some of the objects with increased precision at the cost of precision for others. It has been shown here that, while the above findings may be true in some situations, one might, in a given problem, prefer "repeated designs" to those suggested in [3] and [5].
