P value in jmp

WebP Values. The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested. P is also described in terms of rejecting H0 when it is actually true, however, it is ... WebAug 16, 2024 · For example, the p-value that corresponds to an F-value of 2.358, numerator df = 2, and denominator df = 27 is 0.1138. If this p-value is less than α = .05, we reject the null hypothesis of the ANOVA and conclude that there is a statistically significant difference between the means of the three groups.

WebNov 7, 2024 · Note that the value of the AD statistic is 0.2307 and the p-value is 0.805. The 0.2307 was calculated from the AD formula above. With a p-value of 0.805, you would fail to reject the null and conclude that your data is not different than normal. This would satisfy any assumption of normality you might need for a statistical test.

WebThe p-values take on a value between 0 and 1 and a histogram can be created to get an idea of how the p-values are distributed between 0 and 1. Some typical p-value distributions are shown in the images below. On the x-axis we have histogram bars representing p-values.
