Conclusion
The project investigated average length of Citibike rides by males and females. We used a two-sample T-test to compare male and female ride length, using a dataset of some 3 million rides from June and July 2017. At significance level 0.05, we rejected the null hypothesis that males make rides shorter than or equal to those made by females. This finding is supportive of our original research idea. It appears likely that there is indeed a statistically significant difference. The finding provides motivation for further research. Additional research questions could include whether males make longer rides than females systematically during all times of the week - including during commuting hours and weekends - and whether the lower propensity for long rides is shared by females at younger and older age ranges. Such an extension of the research could help identify specific reasons for shorter rides by females, such as whether this is simply due to less weekday commuting or whether safety concerns on the part of some of the female population is impeding their Citibike use. Based on this analysis, policy measures could be adopted to make Citibike more attractive to females and alleviate the difference in uptake suggested by this study.
