Critical Value - The value that is exceeded by the test statistic with a small probability (significance level). A "look-up" or calculated value of a test statistic (i.e., a test statistic value) that, by construction, has a small probability of occurring (e.g., 5 %) when the null hypothesis of randomness is true.
