TS ISO 3534-1

TS ISO 3534-1 is a terminology standard for the core terms, definitions, and symbols used in statistics and probability. This part focuses on general statistical concepts so that other International Standards can be drafted with a common, consistent language, helping users interpret statistical expressions in the same way across different technical fields.

The role of a common statistical vocabulary

Clear terminology matters in statistics because it reduces ambiguity in data collection, sampling, estimation, hypothesis development, and interpretation of results. In general technical context, the scope includes not only calculation-related terms but also the probability concepts that underpin statistical methods. That means concepts such as events, distributions, random variables, and probability are organised within a shared conceptual framework.

What this scope means in practice

• The standard covers general statistical terms and terms used in probability.
• Its wording is intended to support the drafting of other International Standards.
• It promotes consistent use of concepts in statistical applications.
• As a vocabulary standard, it provides a shared technical language across sectors and documents.

This publication is best understood as a conceptual reference rather than a procedural test method. Its value lies in aligning statistical communication and standardisation work around agreed terminology, rather than prescribing how to perform measurements or analyses.
