Chi Square Test Critical Value Table Look-up


This page finds critical chi square test values for statistical significance decisions.

Select the desired p value.
p = .10 p = .05 p = .01

*** Waiting for results ***


Chi square test scores that are more extreme than the critical value are statistically significant (reject H0). Otherwise, keep the H0 (not significant).

For chi square goodness of fit (columns only), the degrees of freedom are columns (groups) - 1. The test of independence degrees of freedom are (rows - 1) * (columns - 1).
