• B)Using the repeated measures design,we analyze raw scores,whereas using the matched samples design,we analyze difference scores before computing the test statistic for the related samples t test.
• C)Using the repeated measures design,we treat each pair of scores as related;we do not treat each pair of scores as related using the matched samples design.
