In this paper we have proposed a solution to a problem of complex sampling which arises when two sub-populations or groups make up a population. In such cases, in fact, we often know the frame population of only one group and, consequently, only from this group we can draw a random sample by using traditional methods.

Abstract
In this paper we have proposed a solution to a problem of complex sampling which arises when two sub-populations or groups make up a population. In such cases, in fact, we often know the frame population of only one group and, consequently, only from this group we can draw a random sample by using traditional methods.
