Abstract
In this paper, we consider the problem of estimating the expected value of a fuzzy-valued random element in the stratified random sampling from finite populations. To this purpose, we quantify the associated sampling error by means of a generalized measure introduced in a previous paper. We also suggest a way to compare different variates for stratification, as well as to test the adequacy of a certain one.
