| Abstract: | Abstract The problem of “optimum stratification” was discussed by the firstmentioned author in an earlier paper (1). The discussion in that paper was limited to sampling from an infinite population, represented by a density function f{y). The optimum points yi of stratification, for estimating the mean µ using  which gives the stratification points Yi that minimize the sampling variance V y (provided the usual condition for the minimum is fulfilled) |
