In that case, the associated tests' alpha value is less than 0.05. For example, if I chose an alpha of 0.01, then a z test with such an alpha has a critical value of 2.57. If my test yielded a test statistic of 2.3 my p value would be 0.021.

WebFeb 28, 2014 · A p-value is not a probability that the null hypothesis is true. For example, if you took a thousand cases where the null hypothesis is true, half of them will have p < .5. Those half will all be null. Indeed, the idea that p > .95 means that the null hypothesis is "probably true" is equally misleading. WebMar 20, 2024 · The FPR (not the p -value) is the probability that your result occurred by chance.
