The New York Subway System Public Safety and
Improvement Metrics
This project consisted of designing a research study and investigating the likely outcomes of a problem our team faced daily. Being a group of students that commutes to class every day in the New York City subway, we decided to investigate the crime rates within the system and ways to reduce them.
Overview
Our team decided to focus on the issue that has always been prevalent in the NYC subway: crime. The project initially developed an experimental procedure to investigate the mean crime rate difference when a) adding security cameras to all subway cars and b) adding signs mentioning recording progress next to or below security cameras. Appropriate research questions were developed, and plans on how to address them were presented. A complete statistical analysis was carried out, emphasizing the sample size and statistical power of the experiment. Possible recommendations and the extent of the social impact of the investigation were laid out.
The final part of the project included simulating the experiment to generate data sets that would later be analyzed using the techniques described in the first part of the plan.
