Abstract
Abstract An element is sampled from a defined group so that targeting can be effected within a range between a range greater than a first desired frequency and not more than a second desired frequency. Two data bases are established. The second data base contains elements not selected from the first data base. The element set for targeting is defined between element sets from the first data base and the second data base, thereby creating a composite random sampling of the elements. Testing can be effected on the target elements.
