TS 11633

TS 11633 is a vocabulary-and-symbols standard that brings together core terms used in probability and statistics, with a focus on a common statistical language. It supports consistent understanding of sampling, sampling inspection, and the related concepts used in these fields.

A shared conceptual framework for statistical language

In a terminology standard of this kind, the goal is to prevent the same concept from being expressed differently across organisations, reports, or technical practices. Probability theory deals with mathematical descriptions of uncertainty, while general statistics concerns the collection, summarisation, interpretation, and use of data for decision-making. Sampling terminology provides a common vocabulary for defining and describing subsets drawn from a larger population.

Why sampling and inspection terms matter

The scope also includes terms relating to methods of sampling, terms relating to sampling inspection, and some symbols used with them. That distinction matters because sampling describes how representative data are obtained from a population, whereas sampling inspection is aimed at drawing conclusions about quality or conformity from the selected sample. Symbols help keep formulas, distributions, and decision rules concise and consistent across statistical documents and calculations.

This record represents a withdrawn edition of TS 11633 and is associated in subject matter with ISO 3534-1:1993. As a terminology standard, its practical value lies in helping statistical texts use the same concepts with the same meaning, improving clarity across probability, sampling, and statistical application contexts.
