In this paper, we shall use clearly identified random variables required to study the Dorfman-Sterrett procedure first introduced by Sterrett. Based on the identified random variables, we shall derive probability distributions, conditional probability distributions and the expected number of runs (tests) in the Dorfman-Sterrett designs. Using combinatorial theory, we shall derive results obtained by earlier authors in a much simplified version.
