Statistical Computing

  • We will use R for statistical analysis throughout the course
  • We will access R through the RStudio graphical interface; make sure both are installed on your laptop and bring it to every class
  • We will use posit Cloud for quizzes and exams, so you may want to familiarize yourself with it before hand, the good news is that it looks exactly like R Studio

Pre-Class Reading Assignments

  • This course moves quickly—review material before class.
  • Use Perusall to ask questions, help others, and share your insights.
  • Your participation shapes class discussion and deepens your understanding.
  • Aim for at least 3 thoughtful posts (questions, replies, or comments) per reading.
  • Grading is based on effort and thoughtfulness; full effort earns full credit.

In-Class Practice

  • Understanding the concepts really comes from practice
  • Class will be synchronous and in person; class time will be divided between lecture and practice
  • We will use Learning Catalytics so you can practice the concepts during class
  • Graded on participation, not correctness; answer 75% of the questions to get 100% of the credit

Homework

  • Homework due each week Monday at 11:59 pm
  • Automatically graded, three attempts
  • OK to work together, but try the problems on your own first for maximum benefit
  • If you use AI, make sure that you’re understanding what its doing

Checkpoint Quizzes

  • It is critical in this course to stay on top of things and not fall behind
  • Checkpoint Quiz at the start of each class will help you ensure that you are really learning the material, and give you an early heads up if you aren’t
  • You can use RStudio and an index card “cheat sheet” during quizzes (so don’t spend time memorizing anything!)
  • Unit A has 7 Checkpoint Quizzes and Unit B has 6 Checkpoint Quizzes
  • In each unit, we will drop the lowest quiz grade

Mastery Exams

Each unit concludes with a Mastery Exam:

  • Unit A: March 9 or 10, 7-9 PM
  • Unit B: April 30, makeup 8-10 AM, regular 12-2 PM
