Use this calculator for critical values to easily convert a significance level to its corresponding Z value, T score, F-score, or Chi-square value. Outputs the critical region as well. The tool supports one-tailed and two-tailed significance tests / probability values.
In many cases, critical values are required. A critical value often represents a rejection region cut-off value for a hypothesis test – also called a zc value for a confidence interval. For confidence intervals and two-tailed z-tests, you can use the zTable to determine the critical values (zc). Example.
