WebMay 8, 2024 · If your chi-squared d.f. are really large you can use normal tables to get an approximation. For large d.f. $\nu$ the chi-squared distribution is approximately normal with mean $\nu$ and variance $2\nu$. To get the upper 5% value, take the one-tailed 5% critical value for a standard normal ($1.645$) and multiply by $\sqrt{2\nu}$ and add $\nu$.
