P' meaning in statistics

WebThe p -value is a function of the chosen test statistic and is therefore a random variable. If the null hypothesis fixes the probability distribution of precisely, and if that distribution is continuous, then when the null-hypothesis is true, the p-value is uniformly distributed between 0 and 1. Thus, the p -value is not fixed. WebMay 11, 2024 · The higher the F-value in an ANOVA, the higher the variation between sample means relative to the variation within the samples. The higher the F-value, the lower the corresponding p-value. If the p-value is below a certain threshold (e.g. α = .05), we can reject the null hypothesis of the ANOVA and conclude that there is a statistically ...
