Use the preparation materials (I also suggest reviewing the preparation questions for the [Bivariate EDA - Quantitative](BEDAQuant) and [Bivariate EDA - Categorical](BEDACat) 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 items are described when performing a bivariate EDA with quantitative variables?
  2. What must be in x= and y= of aes() in ggplot() to construct a scatterplot?
  3. What function must be added to a ggplot() object to make a scatterplot?
  4. What does shape= in geom_point() do?
  5. What does corr() do?
  6. What must be included as the first argument to corr()?
  7. You must convert the variable to what R data type to properly compute a frequency table for an ordinal categorical variable?
  8. What does factor() do?
  9. What does using levels= in factor do?
  10. What does xtabs() do?
  11. What does percTable() do?
  12. What is the first argument to percTable()?
  13. What does using margin= in percTable() do?
  14. 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).]
