The module helps to decide whether a quantitative characteristics of a material (e.g. size, purity, strength, mass, humidity) satisfies given requirements. Acceptance sampling for variables is useful even for materials, for which no individual pieces can be distinguished (e.g. fluid or gaseous materials). In such cases, a sample of appropriate size from the whole batch is taken. The sample is subsequently analyzed (measured). Size of an individual sample is related to the measurement method and its properties. Sampling has to be done in a random way, keeping in mind that each part of a sampled batch has to have the same probability of becoming a part of a sample.
