WebApr 9, 2024 · 5.99 is the critical value for 2 degrees of freedom and p = 0.05. So any value of $\chi^2$ greater than 5.99 is significant at the 0.05 level.. 220.5 is the critical value for 2 degrees of freedom and p = $1.315 \times 10^{-48}$ so any value greater than 220.5 is significant at that level. The difference is that in one case you are specifying the level first … WebValues with are tabled.
