  • determining a total population of an inventory of members;

    segmenting the total population into a plurality of segments;

    calculating, using the computer, a sample size for each of the plurality of segments based at least in part on the sampling error;

    using a criterion measure for ranking members of each of the plurality of segments;

    generating, using the computer, a set of random numbers for at least one of the plurality of segments, wherein the set is equal to the sample size for the at least one segment; and
