The Study

Back: Background Research     Home      Next: The Study - Data

Our study centered around the following question:

"Is there a correlation between a person's music genre preferences, and their level of procrastination?"

We applied this study to the entire population of Junior at North Olmsted High School. However, by conducting our study as such, our results are only statistically appropriate to Juniors at the high school, and not the entire school.

In order to conduct our study we randomly selected 40 students from the Junior class at NOHS using the randomization feature of Minitab. We then found out the person's first period room number (or 6/7 if the person went to Polaris). Once we had the students, we sent out a survey, which asked the following questions:

2. What genre of music do you listen to most (CIRCLE ONLY ONE):

• Rock (Led Zeppelin)
• Emo (The Night Before)
• Hip-Hop & Rap (Ludacris)
• Pop (John Mayer)
• Country (Kenny Chesney)
• Death Metal (Slayer)

3. Who is your favorite artist from that genre?                                                                                       

 

When conducting our study, we used the following information:

H_o: The true average level of procrastination (based on the scale used in our study) is homogeneous for all genres of music

H_a: The true average level of procrastination (based on the scale used in our study) is different for all genres of music.

We also used an α (alpha) of .05 in our study.

We performed a Chi-Square Goodness-of-Fit test:



After performing our calculations, we can up with the following information:

• X²: 13.41379
• P-Value: 0.009147
• DF: 28

When calculating our Chi-Square test, we came up with the following raw data, which we used to conduct our Chi-Square test:

Genre	Average	Expected
Country	4	3.625
Classical	1	3.625
Death Metal	2	3.625
Rock	3	3.625
Emo	1	3.625
Other	6	3.625
Pop	1	3.625
Rap	8	3.625
