Calculate critical values for Z, T, F, and Chi-square statistics with this online tool. Enter the significance level, the statistic, the degrees of freedom, and the type of test to get the critical value and the critical region.
Find critical values for various hypothesis tests and confidence intervals with this online tool. Enter significance level and degrees of freedom to get t, z, f, chi-square and other critical values in real time.
Find critical values for T, Z, Chi, and F distributions with this online calculator. Enter significance level and degrees of freedom to get left-tailed, right-tailed, and two-tailed P values for different statistical tests.
Critical Value Calculator. This 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 degrees of freedom, and then hit "Calculate for T".
From a t-distribution table, the critical value is 1.734. For a two-tailed test, you need to find the critical value for both tails. The critical values are typically denoted by tα/2 and -tα/2. For example, if α = 0.01 and df = 28, the critical values from a t-distribution table are -2.763 and 2.763, respectively.
Calculate the critical value for different statistical tests based on normal, t, F, and chi-square distributions. Enter the distribution, tails, significance level, mean, standard deviation, and degrees of freedom.
