How long can you hula hoop for?

1. How long can you hula hoop for? By: Sarah Beeson and Lauren Hensel Block 1

2. Introduction We had everyone in the class hula hoop for as long as they could 1 minute (60 seconds) being the longest Time ended when the hula hoop dropped or the contestant reached 60 seconds

3. Quantitative Data Shape: Roughly right-skewed, possible outlier at 60 seconds Center: Median=4.88seconds Spread: IQR=57.32 seconds, Range= 58.03 seconds

4. Normal Model? Our data does not fit a normal model because it is not linear and there are huge gaps between our data points. It is not symmetric. The data is bimodal at 60 seconds, and between 0 and 5 seconds. Also, the center is the median, at 4.88 seconds.

5. Quantitative Data by Gender The females box plot has a larger IQR than that of the males. The female IQR is 57.18, where the male IQR is 27.46. There was one male who reached 60 seconds so this created a possible outlier. The median for males is 4.62 and the median for females is 5.6. The shape is not symmetric.

6. Quantitative Data by Hula Hooping Experience The contestants who have never hula hooped before had a maximum of 5.6 seconds, where the contestants who have hula hooping experience reached the maximum time of 60 seconds. The people who have hula hooped before have more of a range of scores. Although some people had hula hooped before, the minimums for each variable are similar. The shape is not symmetric. The center for those who never hooped before is 3.13, and 15.31 for those who have hooped before. The spread of the people who haven’t hooped before is 2.15, and the spread for those who have is 57.18.

7. Quantitative Data by Partner Shape: right skewed, no outliers Center: Lauren’s median=10.185 Sarah’s median=4.58 Spread: Lauren’s IQR=56.79 Sarah’s IQR=57.34

8. Two-Way Table

9. Marginal Distributions No: 28.9% Yes: 71.1% Female: 50% Male: 50%

10. Conditional Distributions Of the females, 10.5% said no they hadn’t hula hooped before and 89.5% said yes. Of the males, 47.4% said they hadn’t hula hooped before, and 52.6% said yes, they had. Of the people who said no, 18.2% are female, and 81.8% are male. Of the people who said yes, 62.9% are females and 37.04% are males.

11. Independence Our categorical data are dependent of one another. We know this because the two-way table on the previous slide shows that there is not an equal distribution.

12. Possible Errors and Bias Human error with stop watch (starting/stopping too soon/late) Classroom distractions/atmosphere Hindering full potential of contestant Classmates may have avoided this station if they don’t like Hula Hooping Gave second chance to few contestants Messed up immediately, bumped into something or someone

13. Conclusion Overall, we were able to conclude that gender does have an impact on how long one can Hula Hoop for. Females typically were able to Hula Hoop for a longer duration than the males. Also, the dance class categorical variable had little to no effect on the quantity for each contestant. The variable that mostly dictated a contestant’s ability to Hula Hoop is experience; even though some people had Hula Hooped before, they may not have excelled during our experiment.
