What is paired t test? In general mathematics, a paired t-test (also known as a correlated or dependent test) is put to use for the purpose of comparing 2 population means where we are made available with two samples. Of the two samples, observations in one sample can be paired with observations in the other sample.
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.
