TS 11633 ISO 3534-1

TS 11633 ISO 3534-1 is a terminology standard for probability and general statistical terms, together with symbols for a limited number of those terms. Standards of this kind help technical documents use statistical concepts with consistent meaning and provide a shared vocabulary for drafting more specialized standards.

How the vocabulary is organised

The standard brings together core names used in probability theory and general statistics. In practice, that means common statistical concepts such as data, distributions, sampling, estimation and variability are treated within a single vocabulary framework. Symbols are provided only for a limited set of terms, so the document supports notation consistency rather than prescribing a full mathematical notation system.

In general technical use, a vocabulary standard like this matters because it improves comparability across measurement reports, analytical methods and technical specifications. Probability terms describe uncertainty and randomness, while general statistical terms name the processes used to summarise, infer from and interpret data. That distinction is especially useful in engineering, quality control, research and the social sciences, where ambiguous terminology can easily lead to miscommunication.

• Provides shared terminology for probability and general statistics.
• Covers terms that may be used when drafting other international standards.
• Also defines symbols for a limited number of those terms.
• Supports consistent and comparable use of statistical concepts.

This listing is based on ISO 3534-1:1993 and is withdrawn. It therefore reflects a historical terminology framework, but it remains useful for understanding how statistical concepts and symbols have been standardised in a formal vocabulary document.
