Residual Plot: This is no the best model because we can see that the residual plot has a pattern and it isn’t random. Well, did you have a good time! I know you did! Looking back at our one variable analysis, we can see that on average, males run the marathon faster than females do. Females, though, are much closer together in times, the middle 50% of average marathon paces for females fall within 13 minutes of each other, and compared to the men, that is about nine minutes closer together! Now, this surprised us too, but when looking at average marathon pace by age, we can see that the older you get, the quicker you actually run! For every year older you are as a male, your marathon time is predicted to drop by about 3 minutes! For females, your time is predicted to drop by about a whopping 7 minutes! This is amazing, but while the females’ drop-in time is higher than the males, the males still run it quicker overall. Looking through our data, our analysis answers our original question; yes, marathon times do differ by age. Well, looks like I’m running out of space. Thanks for reading!

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
