The paired t-test, also referred to as the paired-samples t-test or dependent t-test For example, you could use a paired t-test to understand whether there was a
Example of paired sample t-test. Let us consider a simple example of what is often termed "pre/post" data or "pretest posttest" data. Suppose you wish to test
A paired t-test is used to compare two population means where you have two samples in which observations in one sample can be paired with observations in the other sample. Before-and-after observations on the same subjects (e.g. students' diagnostic test results before and after a particular module or course).
The dependent t-test (called the paired-samples t-test in SPSS Statistics) For example, you could use a dependent t-test to understand whether there was a
