Here we will reproduce two plots from a fivethirtyeight article titled "Dear Mona, Which State Has The Worst Drivers?". This article has a corresponding GitHub which contains the data. However, it does not contain the code of data wrangling or visualization generation. We will not attempt to reproduce the wrangling; however, the original data can be found at the National Highway Traffic Safety Administration (NHTSA).
To reproduce two of the graphics from the project, please run the file /source/analysis.Rmd. It can be knit in Rstudio to produce the html output. The data will be pulled from fivethirtyeight's data/bad-drivers GitHub as part of the script, so there is no need to download the data manually. The data, taken from file bad-drivers.csv from the repository, is accessed in raw form at https://raw.githubusercontent.com/fivethirtyeight/data/master/bad-drivers/bad-drivers.csv.
We will be utilizing the following variables:
| Variable | Original Source | Notes |
|---|---|---|
| State | 50 states and Washington D.C. | |
| Number.of.drivers.involved.in.fatal.collisions.per.billion.miles | National Highway Traffic Safety Administration, 2012 | Using data per billion miles driven rather than total count to normalize the states |
| Percentage.Of.Drivers.Involved.In.Fatal.Collisions.Who.Were.Speeding | National Highway Traffic Safety Administration, 2009 | Year different than the number of collisions per billion miles |
| Percentage.Of.Drivers.Involved.In.Fatal.Collisions.Who.Were.Alcohol.Impaired | National Highway Traffic Safety Administration, 2012 |
