WebMar 13, 2024 · There are two ways to tell if they are independent: By looking at the p-Value: If the p-Value is less than 0.05, we fail to reject the null hypothesis that the x and y are independent. So for the example output above, (p-Value=2.954e-07), we reject the null hypothesis and conclude that x and y are not independent.
