ISO/TR 16705:2016 describes the necessary steps for contingency table analysis and the method to analyse the relation between categorical variables (including nominal variables and ordinal variables). It provides examples of contingency table analysis. Several illustrations from different fields with different emphasis suggest the procedures of contingency table analysis using different software applications. In ISO/TR 16705:2016, only two-dimensional contingency tables are considered.

Overview

ISO/TR 16705:2016 - "Statistical methods for implementation of Six Sigma - Selected illustrations of contingency table analysis" provides guidance on designing, conducting and interpreting contingency table analysis for categorical data. The technical report focuses on two-dimensional (r × c) contingency tables and illustrates procedures with worked examples from diverse fields. It bridges Six Sigma practice and statistical standards by showing pragmatic workflows and software-oriented illustrations for analysing associations between nominal and ordinal variables.

Key Topics

Scope: Analysis of relationships between two categorical variables (nominal and ordinal); only two-way contingency tables are considered.

Structured workflow: Six basic steps - state objective, list attributes, specify null hypothesis, sampling plan, process and analyse data, conclude.

Sampling plans: Discussion of four sampling scenarios (random counts; fixed n; fixed marginal totals for rows or columns; fixed both row and column margins) and implications for analysis.

Statistical tests and methods:

Chi-square (χ²) test for independence and goodness-of-fit (formula and interpretation included).
Linear trend test for ordinal associations.
Correspondence analysis to explore and visualise associations between categorical levels.

Practical guidance: Emphasis on randomization, confounding factors, and how to prepare categorical (including binned quantitative) data for analysis.

Illustrative annexes: Annexes A–D contain application examples (technical issues after product release, perception studies, customer satisfaction, nonconforming parts) demonstrating real-world use and software workflows.

Practical applications

ISO/TR 16705:2016 is intended for practitioners who need rigorous, practical guidance on categorical data analysis in quality and improvement contexts:

Six Sigma projects (Analyse phase of DMAIC) to test relationships between factors such as defect types, shift, supplier, or inspection outcomes.

Quality engineers & process analysts assessing attribute data and agreement between systems.

Researchers in social sciences, medical studies, and surveys evaluating homogeneity, independence or trends in categorical responses.

Data analysts preparing categorical contingency tables and selecting appropriate tests or multivariate visualisation like correspondence analysis.

Keywords: ISO TR 16705, contingency table analysis, Chi-square test, two-way contingency tables, categorical data analysis, Six Sigma, correspondence analysis, linear trend test.
