Can music help you study?
It has been claimed that listening to music while studying enhances concentration and
consequently helps an individual to absorb more information. To figure this out, your former
high school teacher decided to implement it on a random sample of students. Each randomly
selected student was assigned to study in a classroom under a certain environment
(Classrooms A, B, and C)
Classroom A had constant music being played in the background, classroom B had variable music being played,
and classroom C was a regular class with no music playing. After a month, a test was conducted for all three
groups and their test scores were collected. Aside from determining the test scores of the students, the teacher
also asked the students to personally rate their level of concentration which is measured from 1 to 5, with codes
1 as very low concentration, 2 as low concentration, 3 as moderate concentration, 4 as high concentration, and
5 as very high concentration.
