Comparing arrest rates by weather rating
Do police officers arrest drivers more often when the weather is bad? Let's find out!
- First, you'll calculate the overall arrest rate.
- Then, you'll calculate the arrest rate for each of the weather ratings you previously assigned.
- Finally, you'll add violation type as a second factor in the analysis, to see if that accounts for any differences in the arrest rate.
Since you previously defined a logical order for the weather categories, good < bad < worse
, they will be sorted that way in the results.
