Chapter 9. Measuring associations between two categorical variables
Conceptual metaphors and tests of independence
This chapter focuses on associations between two categorical variables. You will learn how to measure the association strength using odds ratios, Cramér’s V and the φ-coefficient. You will also learn how to test whether the association is statistically significant with the help of the χ2-test and the Fisher exact test. Bar plots, mosaic plots and association plots are used as visualization tools for cross-tabulated data. All these concepts and tools will be illustrated by case studies of metaphoric and non-metaphoric uses of the preposition over and the verb see in different registers.
