WebbProbability is the branch of mathematics that deals with the possibility of any outcome of an event or experiment. There are different types of probabilities. Classical probability states the possible outcome of any event in a classic manner. Webb17 juli 2024 · The test statistic is a number calculated from a statistical test of a hypothesis. It shows how closely your observed data match the distribution expected under the null hypothesis of that statistical test. The test statistic is used to calculate the p value of your results, helping to decide whether to reject your null hypothesis.
