Use the preparation materials (I also suggest reviewing the preparation questions for the [Univariate Summary Statistics](UnivSum) and [Univariate EDA](UnivEDA) modules) to prepare hand-written answers for the following questions. Please ask any questions on the "Questions -- Preparation Guide" on the course Team (see link on the homepage.)
  1. What must be described when performing a univariate EDA for a quantitative variable?
  2. What must be described when performing a univariate EDA for a categorical variable?
  3. What function is used to compute all numerical summaries for a quantitative variable?
  4. What function is used to construct a frequency table for a categorical variable?
  5. What does percTable() do?
  6. What is accomplished with ggplot()?
  7. What type of variable must x= be in ggplot() to make a histogram?
  8. What type of variable must x= be in ggplot() to make a bar chart?
  9. What do you add to ggplot() to make a histogram?
  10. What argument is used to control the width of the bars in a histogram?
  11. What do you add to ggplot() to make a box plot?
  12. What type of variable must x= be in ggplot() to make a box plot?
  13. What does theme_NCStats() do?
  14. What does facet_wrap() do?
  15. What questions do you have from this reading that you would like me to address? [Please be as specific as possible. Don’t just say “everything” or “I don’t understand anything.” Of course, you can ask questions about the reading before class on MS Teams (see link above).]
