In this paper we try to determine if the average trip time for citibike users varies based on the gender in order to see if there is a probable difference in the distance traveled by males and females when using the bike sharing program. We used the citibike trip data for July 2017 and categorized users as "males", "females" and "unknown", in order to run a model that explained trip duration having gender as the independent variable. To test the statistical significance we used non-parametric tests given the distribution of the samples. We found that females have on average trips that last 44 seconds more than men's trips, also that "unknown" gender (unregistered users) against registered users have a 9 minutes difference that probably represents different average trip distance.
