The purpose of the experiment is to derive inferences about the causal effects of a subset of the characteristics of the units of a target population (explanatory characteristics - treatment factors) on characteristics that express the performance of these units (response characteristics). To achieve this objective, the effects of the treatment factors in the sample must manifest themselves as in the target population. This attempt requires the construction of a valid and representative sample of the target population. It is achieved if the experiment plan and its execution satisfy the experiment requirements. These requirements are considered in this article.
