TS ISO 3534-3

TS ISO 3534-3 is the vocabulary part of statistics devoted to design of experiments. It provides a common language for the concepts used when planning and describing experimental studies, helping authors and practitioners use the same technical terms consistently across statistical documents.

Why design-of-experiments terminology matters

Design of experiments is a statistical approach for studying how one or more factors influence a response in a controlled and structured way. In this field, terms such as experiment, factor, level, response, randomization, replication and blocking are central to explaining how a study is arranged and how its results are interpreted. By standardizing these terms, TS ISO 3534-3 supports clear communication between different disciplines and organizations.

What this part covers in practice

The scope states that the standard defines the terms used in design of experiments and may also be used when drafting other International Standards. In other words, it is a terminology reference rather than a prescriptive methodology document. For statistical practice, a shared vocabulary helps make experimental plans, method descriptions and research reports easier to compare and understand.

• Brings together core statistical terms used in experimental design.
• Supports consistent terminology in standards and technical writing.
• Helps describe experimental layouts and statistical plans clearly.
• Serves as a vocabulary reference for related International Standards.
