Introduction

    Citi Bike is a bike sharing service operating in the New York City metro area.  Bikes can be rented from and returned to a collection of stations spread throughout Manhattan, Brooklyn, Queens and Jersey City.  For each unique Citi Bike trip, data is collected for the trip and the rider.  I sought to determine if seniors ( >64 years old) take shorter rides on average than other users of Citi Bike.  I hypothesized that seniors would take shorter rides than younger people, possibly due to tiring quicker or not needing to commute between neighborhoods to work since many seniors are retired.  Knowing if seniors ride Citi Bikes for shorter periods of times could provide valuable insights for spacing of bike docking stations and marketing strategies aimed at seniors, a rapidly growing consumer group.  

Data

    Data from Citi Bike trips was take in January and July of 2016 was collected.  For my analysis the 2 features of interest that I kept were age and trip duration (seconds).  Both features contained outliers that did not represent real bike ride durations or highly improbably ages.
