To compare two paired values (such as in a before-after situation) where both observations are taken from the same or matched subjects, you can perform a paired t- For example, suppose your data contained the variables BEFORE and AFTER, (before and after weight on a diet), for 8 subjects. The hypotheses for this test are:
Ho: mLoss = 0 (The average weight loss was 0)
Ha: mLoss ≠ 0 (The weight loss was different than 0)
For example, the following weight loss data is used in this example
