Cramer’s V Coefficient

Cramer’s V coefficient is used to measure the strength of association between two nominal variables. The value of Cramer’s V statistic satisfies the condition $0\leq V \leq 1$.

• $V$ close to 0 indicate that there is a weak association between the two variables
• $V$ close to 1 indicate that there is a strong association between the two variables.

$$ \begin{aligned} V &= \sqrt{ \frac{\chi^2 /n}{\min(c-1,r-1)} } \end{aligned} $$

where

• $r$ : Number of rows
• $c$ : Number of columns
• $n$ : Total Sample size
• $\chi^2$ : chi-square statistic
