Metallica


 
 

#1

Mr. Lehman wanted to know if his students would do better on a quiz if they listened to Metallica before taking the quiz.

#2

He went to the library and read several studies about the affect of music on young people. Most of the studies said that when students listen to rock and roll before taking tests, they do better on the tests.

#3

He then guessed that the longer a student listened to Metallica before a quiz, the better they would do on the quiz.

#4

He then set up the following experiment. He ask 90 of his students to participate. He broke the 90 students into 3 groups. All of the students were the same age, from the same background, they all took the same quiz, and they were all above average students. There was the same amount of boys and girls in each group. Group #1 did not listen to any music before taking the quiz. Group #2 listened to one hour of metallica before taking the quiz. Group #3 listened to two hours of metallica before taking the quiz.

#5

He then wrote down the following in his notebook. Group #1 had an average of 96% on the quiz. Group #2 had an average of 85% on the quiz. Group #3 had an average of 71% on the quiz.
