If I pick a random T-value, if I take a random T-statistic-- let me write it this way-- there's a 95% chance that a random T-statistic is going to be less than 2.262, and greater than negative 2.262. 95% percent chance. Now when we took this sample, we could also derive a random T-statistic from this. orange park fl shooting

WebJun 9, 2024 · A null distribution is the probability distribution of a test statistic when the null hypothesis of the test is true. All hypothesis tests involve a test statistic. Some common examples are z, t, F, and chi-square. A test statistic summarizes the sample in a single number, which you then compare to the null distribution to calculate a p value. Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these may be.
