Under the null
Web30 Mar 2024 · To determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the significance level α \alpha α.These values are assumed to be at least as extreme at those …

WebOn the graph, I’ve displayed the t-value of 2 from our hypothetical study to see how our sample data compares to the null hypothesis. Under the assumption that the null is true, the t-distribution indicates that our t-value is not the most likely value. However, there still appears to be a realistic chance of observing t-values from -2 to +2. http://www.biostathandbook.com/hypothesistesting.html
Web2 May 2024 · Simulation is well-suited for explaining the sampling distribution of a statistic under the null hypothesis. For Bartlett's sphericity test, the null hypothesis is that the data are a random sample of size N from a multivariate normal population of p uncorrelated variables. Equivalently, the correlation matrix for the population is the p x p ...
