  1. Use pastecs::stat.desc to describe the variable. Include a few sentences about what the variable is and what it’s measuring.
pastecs::stat.desc(County_Data$`Primary Care Physicians Rate`)

  1. Remove NA’s if needed using dplyr:filter (or anything similar)
County_Data_clean<-County_Data |> drop_na(`Primary Care Physicians Rate`) %>% filter(`Primary Care Physicians Rate`>0)
  1. Provide a histogram of the variable (as shown in this lesson)
hist(County_Data_clean$`Primary Care Physicians Rate`)

  1. transform the variable using the log transformation or square root transformation (whatever is more appropriate) using dplyr::mutate or something similar
County_Data_clean<-County_Data_clean %>% mutate(`Primary Care Physicians Rate SQRT`=sqrt(`Primary Care Physicians Rate`))
  1. provide a histogram of the transformed variable
hist(County_Data_clean$`Primary Care Physicians Rate SQRT`)
