WebMar 30, 2024 · Critical values are then the points on the distribution which have the same probability as your test statistic, ... Right-tailed: critical value is the (1-α)-th quantile. Two-tailed test: critical value equals ±(1-α/2)-th quantile of N(0,1). No quantile tables? Use CDF … WebOne may report that the left or right tail probability as the one-tailed p-value, which ultimately corresponds to the direction in which the test statistic deviates from H 0. In a two-tailed test, "extreme" means "either sufficiently small or sufficiently large", and values in either direction are considered significant.
