Overview
ISO 3534-4:2014 - "Statistics - Vocabulary and symbols - Part 4: Survey sampling" is an international standard that defines the terms and symbols used in the field of survey sampling. As part of the ISO 3534 series, it provides a consistent vocabulary for survey methodology, finite population sampling, sampling design and estimation. The standard is intended to be used when drafting other International Standards and by professionals who need a common statistical language for surveys.
Key topics and technical content
ISO 3534-4:2014 focuses on standardized terminology rather than prescriptive methods. Key technical topics covered include:
- Core sampling definitions: population, finite population, subpopulation, superpopulation, sample, sampling unit.
- Design concepts: sampling design, sample size, multi-stage sampling, cluster sampling, stratification and strata.
- Estimation-related terms: terms related to estimators and their properties (see Part 3.2 in the document structure).
- Practical constructs: frames, clusters, strata, and examples that illustrate different sampling contexts (e.g., censuses, checkpoints, polls).
- Supporting materials: Annexes with methodology used to develop the vocabulary, concept diagrams, an index of sampling terms and a bibliography.
- Normative references: cross-references to ISO 3534‑1:2006 and ISO 3534‑2:2006 for related statistical terminology.
The standard contains structured sections for general terms and estimation-related terms, plus informative annexes (methodology, diagrams, alphabetical/indexed term lists) to aid implementation.
Practical applications and users
ISO 3534-4:2014 is practical for anyone who designs, conducts, reports or reviews surveys and sampling studies, including:
- National statistical agencies and census bureaus
- Market researchers, pollsters and social researchers
- Survey methodologists and applied statisticians
- Standards authors, technical writers and documentation teams drafting other ISO standards that reference survey sampling terms
- Academics and educators teaching survey methodology
Using consistent vocabulary from ISO 3534-4 improves clarity in survey protocols, technical reports, standards documents, peer-reviewed papers and cross‑disciplinary collaboration.
