Explain how the paired-samples t test evaluates individual differences and the independent-
samples t test evaluates group differences.
Solution
Use a paired samples t-test when you\'re testing the same people twice, such as
when you give the same person a pre-test (Time 1), then a post-test (Time 2), and you compare
his/her scores at two different times (to see if there\'s a significant difference between the scores
at Time 1 vs. the scores at Time 2). Use an independent samples t-test when you\'re testing
different people\'s scores (such as men vs. women) to see if there\'s a significant difference
between their scores. It doesn\'t have to do with whether the sampling is random. I hope that
helps!.
