What is the Chi-Square Distribution Calculator?

The Chi-Square Distribution Calculator allows users to evaluate the significance of observed data against expected outcomes by calculating the p-value for a given chi-square statistic and degrees of freedom, which is commonly used in tests of independence or goodness-of-fit. By entering the chi-square value, degrees of freedom, and selecting the type of test—right-tailed, left-tailed, or two-tailed—the calculator instantly computes the corresponding p-value, helping students, researchers, and analysts quickly determine whether the observed deviations are statistically significant and supporting hypothesis testing without the need for complex tables or manual calculations.

How to Use:

1. Enter Chi-Square Value (χ²): Type the calculated chi-square statistic.
2. Enter Degrees of Freedom (df): Provide the appropriate degrees of freedom.
3. Select Test Type: Choose right-tailed, left-tailed, or two-tailed based on your analysis.
4. Click Calculate: The tool computes the p-value immediately.
5. Check Output: The result displays the chi-square value, degrees of freedom, and p-value for interpretation.
