Explain in which conditions a paired t test is used for the mean difference between two related populations?© BrainMass Inc. brainmass.com June 4, 2020, 2:33 am ad1c9bdddf
A paired t test (or repeated measures t test) is used when you have a "before and after" type of experimental design. That is to say that you have the same sample population, but they are measured at two different times and the results are then compared using the t test. The mean from before is compared with the mean ...
This solution explains the experimental design that is suitable for use of a paired t-test.
