19.01 Is it a random sample or several random samples?

The MRVO uses both the singular and the plural in § 31. In fact, it is the same whether one speaks of several random samples or of a sample with several (at least two) components. In order to better differentiate between the various aspects (see FAQ 19.03), the Accreditation Council prefers to use the plural as in the title of § 31 MRVO.
