Bivariate Data Project By: Emma Dennis The graph of my data has a positive association. It’s kind of hard to tell because many people interpret it to be a straight line, but if you look really carefully, it’s a positive association. It’s awfully strong, with outliers that are close to the line of best fit. I graphed the top 50 runner's age and time on a scatter plot to see if there was any association. The data I used was from the 2012 Franklin Run Walk Crawl. The Research Question: Association? The Graph: The Data: Does your age affect your time in a 5k? http://www.coolrunning.com/results/12/ma/Jul21_WillNo_set1.shtml Correlation Coefficient: r=.1259175601 Residuals? In this example there are residuals for many reasons. One, being because we have a lurking variable. We do not know the exact physical condition of each runner. This is why there are older runners placing higher than younger runners. The older runners may have more experience, and that may be why they are placing higher than the more inexperienced runners. Conclusion: In the end, a person’s age does affect their time in the 5K. The graph seems to be a straight line because we do not know the physical condition of each runner (the lurking variable), but we can infer that the age of a runner does affect their time. All in all, there is a better chance that a younger runner ran faster than someone older than them. Correlation Determination: r²= .0158552319 LSRL: y=0.19x+20.47
