Assignment 8 – Myojung Chung

For Assignment 8, I analyzed the relationship between snowfall and car accident in the Onondaga county. This is based on my personal experience – whenever it snows, I have a huge fear of car accident. But is it only me? Or is there really a causal relationship between snow and car accident?

But clearly, there is a link between snowfall and car accidents – so we should drive more safely when it snows!

Data are from the following:
Snow precipitation: Community Collaborative Rain, Hail and Snow Network
