Tailed distribution
Web13 Apr 2024 · A chi-square distribution table is a continuous probability distribution. The shape of a chi-square distribution table depends on its degrees of freedom. You can use chi-square tests to compare the difference between expected and observed results. Chi-square tests can be either one-tailed or two-tailed. Definition: Chi-square distribution table
