1. Head Banger Lauren Hoover & ChelseyProvencher

2. The Task • The subject must get as many steps as possible on a pedometer attached to a headband around their head. • They can move their head whichever way they want • They are given one minute to complete the task • We recorded number of steps achieved, gender, number of concerts attended by ranges (0-2, 3-4, 5+), and favorite type of music

3. Our Test • The point of our test is to see if there is a correlation gender, type of music the subject listens to, number of concerts attended and the ability to bang their heads. We predicted that those who listen to metal or rock and those who have attended more concerts would get more steps on the pedometer than those who listen to other music.

4. Overall Data Shape: unimodal, slightly right skewed Center: Median – 137 headbangs Range: (102-209)

5. Normality • Our data is not normal because it is not linear. The line curves.

6. Data vs. Gender Comparison: Females overall were not able to achieve as many head bangs as the males. The 1st quartile of the females starts lower than the male’s and the median also lower.

7. Data vs. Concerts Comparison: The three ranges of number of concerts attended all have around the same median. The group of people who went to zero to two concerts has the smallest range while the group of people who went to five or more concerts had the largest range.

8. Chelsey vs. Lauren Comparison: Chelsey’s range is larger than Lauren’s but this includes three outlying points. Lauren’s has no outliers and a great median than that of Chelsey’s data.

9. Two-Way Table of Categorical Data

10. Marginal Distribution NUMBER OF CONCERTS ATTENDED (0-2): 15/36=41.67% (3-4): 9/36=25% (5+): 12/36=33.33% GENDER Males: 17/36= 47.22% Females: 19/36=52.77%

11. Conditional Distribution The number of concerts attended is dependent on gender. People that went to (0-2) Concerts: 33% female, 67% male People that went to (3-4) Concerts: 56% female, 44% male People that went to (5+) Concerts: 75% female, 25% male Of the females, 26% went to (0-2) concerts, 26% went to (3-4) concerts, and 47% have been to (5+) Of the males, 58% went to (0-2) concerts, 24% went to (3-4) concerts, and 18% have been to (5+)
