Our question was how many songs people have bought in the past month vs. how many hours they have worked to earn money. The population we chose for our questionnaire was 30 high school students. We chose this because they will not all have the same results for each category. High school students also pay more attention to new music, and buying c.d’s is the norm for students. Adults with jobs tend to not pay as much attention to the music world and are too busy to keep up.

Potential bias would be that we picked our friends instead of a variety of people with different interests. Also things that could have been more bias are that at music stores or on iTunes. They try to sell the more popular music and they don’t always have the less known artists so some people don’t go on iTunes or shop at stores. Instead they have to go to a special website or download it for free.

Total Days on Vacation

Linear Reg:y=2.617x+8.795r=.52467

Question #1 summary• For this part of the project we wondered if there is a relation

between Times on Vacation VS. Total Days on Vacation. There was a very big range for both. When we did a Linear Regression we got an r value of .52467. This isn’t terribly bad but it wasn’t as good as we hoped. The mean of # of times on vacation is 2.95 while the mean for total days on vacation is 16.51.

• If we were to make a box and whisker chart this is the data you would find:Standard Deviation: 2.35 Median:2 Mode:2.9

Range: 12• There is an average of about 3 vacations people take per year • This shows that most people only go on 2-3 vacations a year.

There is an outlier of 10 and 12 vacations in a year.

Bar Graph

Bar Graph SummaryThis bar graph shows the populations preference of the stores

given to them to choose. The numbers varied a lot in our stastical data, but an interesting fact is that Pacsun never got ranked

below a 4. For the most

part we saw that girls

chose Forever 21 or Aber-

crombie & Fitch as their

number one ranked store.

For boys the top ranked

store was either Pacsun

or Abercrombie & Fitch.

The store that the population liked least was by far Hot Topic.

Overall, we think that the more time people spend on the computer, the less time they spend on other things such as homework. People who spend more time on the computer rather

than spending time doing homework tend to not care about if their grades are good or bad. They tend to care more about the opposite gender or other social activities. People who

spend more time doing homework tend to spend more time with their families, and they tend to care more about grades. People in our school tend to care about their social life rather than anything else, which is expected for this age group. We also noticed that when we

interviewed the juniors, as apposed to sophomores or freshmen, they tend to care the least about family, and more about their grades. For question number 1, about how much time people spend on homework, the average (mean) was 4.6 hours, and the range was 27. For

the part of the question about how much time they spend on the computer, the average (mean) was 7.8 hours, and the range was 50. The standard deviation for the first part of the question was 4.8, which leaves us with a confidence interval of (3.4, 5.8), and for a person

who spends, per say, about 27 hours of homework a week, their z score would be .9999, and if someone did 0 hours of homework a week, their z score would be .1685. The standard deviation for the second part of the question is 8.09, which leaves us with a confidence

interval of (2.5, 6.6), and for a person who spends 50 hours on the computer a week, their z score is .9999, and for a person who spends 0 hours on the computer a week, their z score is

.1685.

For this report, I handed out half of the survey questionnaire's to high school students during lunch and in some of my classes. I made a scatter plot for question number 1 on Microsoft excel and did a linear regression for it. For question number 3 Maddie and I made a pie chart also on Microsoft excel. I wrote the summary for question 1. Maddie and I both contributed to the 3rd question summary and the overall summary. I also made the cover page with Indiana Jones.
