Experiment #2
question: do different types of music affect how well a person can do his/her homework?
hypothesis: music that does not have a strong beat makes concentrating on a homework assignment easier.
music with heavy beats makes concentration more difficult.
experiment:
sara lilia pulled out four different cd's to find out which type her to finish her homework the
fastest. the first cd was rock, the second reggaeton, the third classical, and the fourth was cumbia. she chose a
math assignment that required concentration.
sara lilia used a stopwatch with an alarm to make sure that she only listened to each cd for 5 minutes.
each time the alarm went off, sara lilia recorded how many problems she was able to finish.
at the end of the experiment, she found that she was able to concentrate the most with the classical
music, then the rock, and the cumbia. she noticed that she did not concentrate much at all with the reggaeton
and felt like dancing and singing along instead of working.
