They selected a random sample of 30 students from their medium-sized high school to participate. Each subject was given 10 minutes to memorize two dif- ferent lists of 20 words, once while listening to music and once in silence. The order of the two word lists was determined at random; so was the order of the treatments. The difference in the number of words recalled (music – silence) was recorded for each subject. A paired t test on the differences yielded t = -3.01 and P-value 0.0027.
