Project Description

Using data collected from the State of Iowa, you will apply the data wrangling and visualization skills you learned in Introduction to the Tidyverse. Anyone with some familiarity with the tidyverse suite of R packages, specifically dplyr and ggplot2 will be able to successfully complete this project. You will group, summarize, and visualize data on breath alcohol tests in Ames, Iowa, (home of Iowa State University) from 2013-2017. Some questions you will answer include, "What is the highest recorded value?" and "When do breath alcohol tests occur most?"
