P value symbol
WebA p-value is "the probability for a given statistical model that, when the null hypothesis is true, the statistical summary would be the same as or of greater magnitude than the actual observed results." Source Thus, the p-value is defined as P r ( X ≥ x H) for a one sided (right tailed) test. WebMay 9, 2024 · The “P” in P-value means probability.
