• In-class exercises will now largely center around chapters of the textbook An Introduction to Statistical and Data Sciences by Kim and Ismay. I encourage you to work together, as collaborative learning is many times more effective than learning in isolation.
  • If you weren’t able to complete the in-class exercises during class time, please do so on your own before the next lecture.
  • In particular, do the “Learning Checks” indicated by the green boxes. We will revisit them the following lecture.


  • Slides on the tidy data format
  • Packages to install: nycflights13. See the slides from Lec03 on how to install packages.
