The critical value calculator helps you find the one- and two-tailed critical values for the most widespread statistical tests.

Calculates critical values for z, t, chi-square, f and r. Allows you to set your own significance level.

Calculates critical values and draws distribution chart for Z, t, F and chi-squared distributions. Two-tails, left tail or right tail. Step-by-step calculation

Use this best critical value calculator to determine the critical value for the z, t, chi-square, f, and r distributions. Unless you know how to identify critical value.

A critical value defines regions in the sampling distribution of a test statistic. They account for uncertainty in sample data.

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.

This calculator helps you find the critical values for various distributions (Z, t, Chi-Square, and F) based on your chosen significance level (alpha) and degrees of freedom.

Get the critical values associated with a particular significance level (alpha) and statistical distributions with the critical value calculator.

Calculate critical values for statistical hypothesis testing with this Critical Value Calculator. Input confidence level, degrees of freedom, and distribution type for accurate results in normal, t, chi …
