    Understanding the Uniform Distribution of P-Values in Hypothesis Testing

    I read the following statement from wiki,but I don't know how to get this. "when a p-value is used as a test statistic for a simple null hypothesis, and the distribution of the test statistic is continuous, then the test statistic (p-value) is uniformly distributed between 0 and 1 if the null...
