Comparing frisk rates by gender
In this exercise, you'll compare the rates at which female and male drivers are frisked during a search. Are males frisked more often than females, perhaps because police officers consider them to be higher risk?
Before doing any calculations, it's important to filter the DataFrame to only include the relevant subset of data, namely stops in which a search was conducted.

Exercise instructions
- Create a DataFrame,
searched
, that only contains rows in whichsearch_conducted
isTrue
. - Take the mean of the
frisk
column to find out what percentage of searches included a frisk. - Calculate the frisk rate for each gender using a
.groupby()
.
