5.2.2 · Strength of a RelationshipCramer's V
Cramer's V
r — number of rows
c — number of columns
The higher V, the stronger the relationship between the variables.
Values > 0.30 are considered substantial.
V values have an upper limit of 1, but they too can actually reach it only for 2×2 tables.
Problems:
- V is not standardized and depends on the table dimensions.
- V values from different studies cannot be compared with one another.
In our example:
The relationship is not particularly strong.
