A Paired T-Test, additionally referred to as correlated pair t-test/paired sample t-test/dependent t-test, is a statistical procedure that runs a test on dependent variables.

12.1 - One Variance; 12.2 - Two Variances; 12.3 - Using Paired t-test using Minitab Introduction. The paired t-test (also known as the paired-samples t-test or dependent t-test) determines whether there is a statistically significant difference in the mean of a dependent variable between two related groups. 14.1.2 Paired t-test using the one sample t-test on the difference series. When we selected a paired t-test, R will automatically create a difference series to use, and apply the one sample t-test to the difference series. To check this we can manually create the difference series and then apply the one sample t-test directly to the difference series that we create.
