Nettet13. feb. 2024 · Left-tailed test: p-value = cdf (x). Right-tailed test: p-value = 1 - cdf (x). Two-tailed test: p-value = 2 × min {cdf (x) , 1 - cdf (x)}. If the distribution of the test statistic under H 0 is symmetric about 0, then a two-sided p-value can be simplified to p-value = 2 × cdf (- x ), or, equivalently, as p-value = 2 - 2 × cdf ( x ). NettetLeft-Tailed.
