Dependent sample t-test

Explanation:

The Dependent sample t-test compares the mean score of measurements in one group to that of another other group. It mainly used when analyzing comparable sample units as it pairs repeatable observations within a time frame.

For example, a researcher administered a measure of working memory to a group of subjects at 8am on Day 1 of the study and then again at 8am on Day 2 of the study, after keeping the subjects awake the entire night.
