Critical chi-square value calculator
WebThis quick calculator allows you to calculate a critical valus for the z, t, chi-square, f and r distributions. Critical Value for T Select your significance level (1-tailed), input your … WebIf your chi-square calculated value is greater than the chi-square critical value, then you reject your null hypothesis. If your chi-square calculated value is less than the chi-square critical value, then you "fail to reject" your null hypothesis.
