What is the relationship between Cramér's V and the Chi-square test?
- Cramér's V is the inverse of the Chi-square statistic
- Cramér's V is the square of the Chi-square statistic
- Cramér's V is the square root of the Chi-square statistic divided by the sample size and the minimum of rows and columns minus 1
- There is no relationship between Cramér's V and the Chi-square test
