Abstract
The idea of this project comes from the curiosity of the generation distribution of Citi-bike user, we divide the data into 2 categories, pre-90s and post-90s to see whether younger generation less likely to use Citi-bike to commute, and what is their characters in trip duration, trip time and route pattern. Through the analysis, we reject the null hypothesis that the proportion of pre-90s biking on weekends is the same or higher than the proportion of post-90s biking on weekends(alpha=0.05), hence, we are reasonable to conclude that post-90s are less likely to use Citi-bike for commuting than pre-90s.
