🧪 Coding Assignments There are 2 coding assignments I completed this week that are graded. I did calculations like var, mean, and utilized pipes. They are submitted to an automated grading system (CodeGrade) that is very finicky:
- nycflights13 utilizes the tidyverse and nycflights13 packages.
- msleep utilizes the tidyverse packages which has the msleep dataset already inside it.
💯 Exam
- An exam on Model-Building & Assumptions with 11 questions. Lots of fill in the blanks and questions with multiple answers.
- You can take the exam as many times as needed to get the score you want, but each test has different questions. I took the exam 1 time. Final score was 90.00% as I missed one. You have until the end of the semester to take all your exams. I’ll see how I do when I start turning in graded assignments on if I need to retake this test.
🔥 Summary
- Another easy week with just watching videos, completing a few problems, and a short test.
Stay tuned for week 5…
