A professor at UCI wants to see what students really remember from their elementary school days, the stuff that was taught or the stuff that was popular at the time. She put together two tests, one with elementary school education questions and one about pop culture from that time. She got a sample of 9 students and had them take both tests. What test does she use? 

Pop Culture:      65          52          90          72          59          79          80          68          76

Education:          65          74          87          96          84          80          82          89          75.
