What is a Critical Value Calculator?
The Critical Value Calculator helps you determine the critical value for statistical hypothesis testing. It works for various distributions like t-distribution, z-distribution, and chi-square distribution. You can input your significance level (alpha) and degrees of freedom (df) to find the corresponding critical value.

What is the Critical Value Calculator?
The critical value calculator is a tool used to find the critical value corresponding to a given significance level and degrees of freedom for different statistical distributions.
How to Use the Critical Value Calculator?
To use this critical value calculator, select the desired distribution (Z, T, or Chi-Square), enter the significance level (alpha), and the degrees of freedom. Then click "Calculate" to get the critical value.
What is the Formula of the Critical Value Calculator?
The formula for finding critical values depends on the distribution:
- For Z-Distribution, the critical value is obtained using Z-tables based on the alpha value.
- For T-Distribution, it uses the t-table based on alpha and degrees of freedom.
- For Chi-Square, the critical value is determined using the chi-square distribution table based on degrees of freedom and alpha.
