I am plotting the number of accidents happened daily vs the daily precipitation for Car collision data of New York City for the year 2013 using scatter plot. I found a strange chart which I am not able to understand.

Can anyone please tell me what kind of relationship is there among the daily precipitation and daily accidents.

    $\begingroup$ It may make more sense to plot number of accidents per car on the road, as people tend to drive less when there is rain. $\endgroup$ Commented Dec 12, 2015 at 4:13

I agree with Matthew. I'd first look into if there is a correlation of accidents with rain/no rain. Not sure if amount of rain would influence that much.
