WebbLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833.

WebbChi-Squared is a continuous probability distribution. It is also used heavily in the statistical inference. We utilise chi-squared distribution when we are interested in confidence intervals and their standard deviation. Just like student-t distribution, the chi-squared distribution is also closely related to the standard normal distribution.
