▶︎ The paired t-test is used to compare the means of 2 matched, paired, or dependent groups. It essentially becomes the univariate (one sample) t-test, by taking the difference in observations in the 2 groups and then conducting a test on the mean difference.
▶︎ The paired t-test is also known as paired two-sample t-test, paired-sample t-test or dependent sample t-test.
▶︎ We also cover building a confidence interval for the mean difference, as well as how this can be used to test a hypothesis.
▶︎ While we do show the calculations in the video, the video focuses on the concepts underlying the test.
▶︎ Common applications of the paired sample t-test include case-control studies or repeated-measures designs.
