Everyone listens to music and many of us get lyrics stuck in our head that distract us when trying to concentrate on school work. We wanted to know how this affected our grades.

Some people believe that listening to music can increase their level of concentration while others believe that music can distract them from their work. As a group we believe that both of these ideas make sense and are reasonable; however, we wanted to research and find out which one is more accurate. We can up with these questions that we believe students may have:

1. Does music distract us when we are working or does it help us do better?

2. Will listening to music for a long period of time effect me in the future? Will I be able to concentrate more or less even when I'm not listening to music?

3. If music does effect us, is there a specific type of music that will impact is the most?

Grade point average vs. Hours spend listening to music

We calculated and found that the IQR of both the ELA and Math average is 12 which means that using this is not that reliable because the graph is so spread out. This graph is skewed because the whiskers of the dot plot are uneven, the whisker from the minimum to quartile one is larger than the whicker from Quartile 3 and maximum.

We decided to make a scattered plot to see if there is a relationship between the two. The results we received were very unexpected because we thought that music would affect us in a positive or negative, but from the data of the 17 students we surveyed and plotted we realized that there is really no relationship.

We used a dot plot to record the data of the grade average in math in ela because we wanted to see if that would be a reliable data to use. To find that we had to use a dot plot and find the IQR to see how spread out it was.

We created a residual of both the Math and Ela data. We realized that the residual plot was scattered and that means that the data is linear however, that doesn't mean that the linear line is strong because the correlation coefficient was 0.01 and 0.04 which showed that there was not a negative or positive linear relationship. The maximum number of hours a person we surveyed listened to music was 9 hours and their average in ela was 80. However, a person who listened to music for only 2 hours also had an average in ela of 80. With this we can infer that listening to music more will not necessarily increase or decrease the grade.

We chose to create a scatter plot to show music affect the grade average because we were comparing two variables and using a scatter plot to record that data is the easiest. The other options were a dot plot or a frequency table, but those wouldn't allow us to record two variable numerical data.

We created a frequency table to compare two groups of categorical data. This shows that listening to music does not allow a person to complete their homework faster. Most of the time they either do it slower or its the same amount of time. 50% of all the student we collected data on completed their homework slower and 39.58% of the students completed their homework in the same time they would if they didn't listen to music. This is another piece of evidence to show that music doesn't really help a student complete her homework faster. Many of the time they would complete their homework in the same time or slower.

We used a frequency table to compare the two group of data because these two data were both categorical which meant that we need to create a graph that we can collect data by tallying. We collected the data and organized it using the table by tallying them and then converting them to percents based on the total.

According to NY times It says, "Those who were moderately skilled at their jobs benefited the most, while experts saw little or no effect." This proves that the data we have collected should've been expected because the "R" or the correlation coefficient of the two graphs were 0.01 and and 0.04 which shows that they do not show a strong linear relationship. This means that the amount of time a person listens to music does not effect their grade in school. Sometimes people say that listening to music helps them concentrate, but it may just be for an individual because as a group there is defiantly not a big impact music has on grades. To all the parents who believe that your child shouldn't listen to music while working, here is data collected from teenage students showing that music doesn't affect grades. Therefore, it shouldn't be a problem if your child listens to music while doing school work or studying.
