Another key distinction between experimental and quasi-experimental designs is the presence of a control group. It involves selecting samples and determining the best estimator based on a given criterion. Just as we needed a quantitative measure of centrality, so also do we require a quantitative index of variability. If there is only one source of variability in the experimental units, and it is not possible to have number of homogeneous experimental units equal to the number of treatments, then recourse is made to incomplete block design as a map used in finding answers to the research questions and planning the methods by which the answers will be obtained and how the results will be treated and reported.
