Project Description

In the Who Is Drunk and When in Ames, Iowa? project, you looked at breathalyzer test data from the State of Iowa. There was a lot of date-time manipulation that was hidden behind-the-scenes in that dataset. In this project, you will proceed to uncover temporal trends in the Ames breath alcohol data.

Anyone with familiarity with the lubridate, dplyr, and ggplot2 packages will be able to complete this project successfully. You will manipulate the dates and times in the breath alcohol data to answer questions such as, "What day has the most tests?", "at which hour of the day are breath alcohol tests most common?", and "are blood alcohol content (BAC) results higher on days when Iowa State University's football team plays?"
