Data Analysis and Visualization of New York Citi Bikers Dataset

In this project, I am analyzing data collected by Citi Bike to answer the following questions:

  • What are the most popular pick-up locations across the city for NY Citi Bike rental?
  • How does the average trip duration vary across different age groups?
  • Which age group rents the most bikes?
  • How does bike rental vary across the two user groups (one-time users vs long-term subscribers) on different days of the week?
  • Does user age impact the average bike trip duration?
This analysis is both done in Google sheets and Jupyter Notebook.
