One thing that police do is make traffic stops. There are many different reasons that the police might choose to pull someone over and in some cases give the driver a ticket. Is their decision affected by gender? race? socio-economic status? time of day? type of car? Statistics is one way to answer these questions but it can also be used to purposely mislead people about the answers to these questions.

"There are three types of lies - lies, damn lies, and statistics" (attributed to Mark Twain, maybe aprocryphal)

We’re going to look at some Evanston Police Department (EPD) data about traffic stops between 1/1/2020 and 7/23/2020 and try to come up with some truthful answers.
