The concept of analytical sample surveys is discussed in general, and a double sampling scheme is proposed for certain situations. Emphasis is placed on the presentation of a method which can be used to solve a certain class of problems. It is assumed that the subgroups of the population which are to be compared form a one-way classification, and are not identifiable in advance of drawing a simple random sample from the population. With double sampling, a large sample is selected, and the group to which each element belongs is identified. Then a subsample is selected within each of the groups according to a sampling rule specified in advance. It is desired to find those values of the preliminary and main sample sizes which will maximize some precision statement subject to a given budget. Approximate procedures to secure quick and reliable solutions are given. The validity of the approximations is also investigated.
