Conduct the Chi-Square Test of Independence

chisq.test(tab)

## 
##  Pearson's Chi-squared test with Yates' continuity correction
## 
## data:  tab
## X-squared = 0.040064, df = 1, p-value = 0.8414

Cramer’s V (Effect Size)
P value 0.8414>0.05 so it is not statistically significant so there is no need to calculate Effect size
Interpret and Report the Results
The Chi-Square Test of Independence indicated there was/ was not a significant association between gender and voting behavior, χ²(1) = 0.040064, p = 0.8414.
