TS 11633

TS 11633 is a terminology standard for statistics that brings together terms and selected symbols used in the field. It focuses on concepts used in probability theory, general statistical terms, general terms connected with sampling methods, and terms relating to sampling inspection. In practice, this supports a common understanding of statistical language in reporting, data analysis, quality work, and technical documentation.

How the terminology is organised

The standard is centered on concepts rather than procedures. Probability provides the mathematical language of uncertainty, while general statistical terms cover the core ideas used to describe, summarise, and interpret data. Sampling-related terminology addresses how observations are drawn from a population, and sampling inspection terminology concerns decisions made from sample results. Together, these areas form the conceptual backbone of many statistical applications.

Symbols and practical context

By including some associated symbols as well as terms, the standard helps keep notation aligned with meaning. That matters in technical writing because statistical symbols can carry different conventions across disciplines if they are not defined consistently. In general technical use, a vocabulary standard like this is valuable in education, research, industrial inspection, and public statistics because it reduces ambiguity without prescribing a single calculation method. TS 11633 was linked to ISO 3534-1:1993 and is now withdrawn.
