Web21.2 Hypothesis Test. The paired samples t-test really is just a special kind of one-sample t-test, where we will compute a difference score \(d=y-x\) and perform the t-test (or compute a confidence interval) on the differences \(d\).This is the most basic kind of repeated measures analysis; more advanced methods that won’t be considered in this class include … WebMar 4, 2024 · When performing a hypothesis test, you set the threshold for concluding significance, say at 0.05 or 0.1. If the p-value is less than the threshold, then you reject the Null hypothesis. You cannot make a statement like "I am 95% confident the null hypothesis is false". The validity of the null hypothesis is judged by the p-value primarily. WebThe null hypothesis for the independent samples t-test is μ 1 = μ 2.So it assumes the means are equal. With the paired t test, the null hypothesis is that the pairwise difference … the antn
