TS ISO 3534-3

TS ISO 3534-3 is a vocabulary standard that defines statistical terms and symbols used in the field of design of experiments. It provides a common language for concepts in experimental design, helping reduce ambiguity when planning studies, analysing data, and interpreting results.

The role of terminology in experimental design

Design of experiments is a statistical approach for arranging variables systematically so that effects can be studied with confidence. Terms such as factor, level, response, randomization, and replication describe how an experiment is structured and how its data are assessed. A terminology standard like this helps prevent the same concept from being labelled differently across disciplines or documents.

What this standard contributes

Based on the supplied scope, this standard contains definitions of terms used in the field of design of experiments and may be used when preparing other standards. In other words, it is primarily a harmonized vocabulary source rather than a methods standard that prescribes experimental procedures in detail. Such terminology standards support consistency in later method or application standards by giving authors a shared set of definitions.

The withdrawn status of TS ISO 3534-3 indicates that it represents a historical terminology framework. Even so, design of experiments remains a core statistical tool in scientific research, quality control, process improvement, and industrial optimization.
