Null Hypothesis for the Chi-Square Independence TestA chi-square independence test evaluates if two categorical variables are associated in some population. Well therefore try to refute the null hypothesis that two categorical variables are (perfectly) independent in some population. If this is true and we draw a sample from this population, then we may see some association between these variables in our sample. This is because samples tend to differ somewhat from the populations from which theyre drawn.However, a strong association between variables is unlikely to occur in a sample if the variables are independent in the entire population. If we do observe this anyway, well conclude that the variables probably arent independent in our population after all. That is, well reject the null hypothesi...
