Analysis of Data that is in the Form of Categories Part II: Beyond the 2*2 Contingency Table—Partitioning Chi-Square Tests

Abstract

This article extends the analysis of 2*2 tables considered in the preceding paper of this three-part series. The methods described in the previous paper for analysis of frequency counts of categorical variables in 2*2 tables, including overall tests, partitioned tests, odds ratios, and estimation of required sample size, are applied to tables with multiple levels, such as those with more than two response factors and/or more than two levels for each factor.

Keywords:

• Categorical data
• Multiple level tables
• Partitioning chi-square analyses
