Webb18 maj 2024 · A p-value is the probability that, if the null hypothesis were true, we would observe a statistic at least as extreme as the one observed. To calculate a p-value we use the appropriate software or statistical table that corresponds with our test statistic. For example, we would use a standard normal distribution when calculating a z test statistic.
