Exam 3

STA 210 - Summer 2022



Exam 3 is released on Friday, June 17 at 9 am ET and must be completed by Mon, June 20 at 11:59 pm.

The exam will consist of two parts:

  1. Part 1 - Conceptual: Multiple choice questions on Sakai test and quizzes.
    • Go to Sakai to complete Part 1 of the exam.
    • This portion is comprised of 10 multiple choice / fill in the blank questions may only be submitted one time, so start it when you can set aside ~30 minutes to work on it. You will likely be done quicker but it’s best to set aside ample time.
  2. Part 2 - Applied: Data analysis in RStudio and submitted in Gradescope, like a usual lab and homework.
    • Go to the GitHub organization for the course and find the exam-3- repo to complete Part 2 of your exam.
    • Add your answers to the exam-3.qmd file in your repo.
    • You can work on this portion at your own pace and come back to it however many times you like until the deadline. I recommend setting aside ~2 hours. You will likely be done quicker, but it’s best to set aside ample time.

Both portions must be completed and submitted by Mon, June 20 at 11:59 pm. Late work will only be accepted in the case of of extenuating circumstances and notification from your academic dean.

🍀 Good luck! 🍀
