Next, I decided to narrow the scope of my analysis by focusing on ride duration (measured in seconds under column "tripduration") for rides taken by male CitiBike riders born between 1965 and 1996. I chose this age range because it includes both Millenials and Generation Xers. (Although there is no universally agreed upon range of years that define Millenials and Generation X, for this analysis I adopted the standards set by the Pew Research Center, which defines Millenials as individuals born between 1981 and 1996 and Generation X as individuals born between 1965 and 1980 -
