๐๏ธ Week 07 - Data Frame Manipulation, Combining Data Practice II
More data frame manipulation, continuing into tidyr for reshaping data and a second round of combining-data practice.
| Date | Time | Format | Topic |
|---|---|---|---|
| Thu, Nov 5 | 1:30-3:05 pm | Lecture | Data Frame Manipulation with dplyr, mid-quarter check-ins begin |
| Tue, Nov 10 | 9:50-10:55 am | DS | Practice: Data Frame Manipulation with dplyr |
| Tue, Nov 10 | 1:30-3:05 pm | Lecture | Combining data practice II |
Solve the Tuesday-morning DS on your own without generative AI and upload your PDFs to Canvas (printing is optional). Thursday opens with open time for your questions about DS 6 (not graded). Tuesday afternoon opens with the DS 7 check on laptops: you swap with a classmate, explain what you did, discuss the differences, and agree on the hardest topic. Bring your laptop, charged, to both.
๐ค AI & Learning This Week
AI status this week: No AI for the DS and check-ins.
Why: The mid-quarter check-in is a short conversation about your code and choices. It is the most direct way to see what you have learned so far.
This week:
- Mid-quarter check-ins are mandatory, for everyone. They are Thu, Nov 5 and during the OH time. Bring your rendered report and your repository.
- Questions you can expect: walk me through this pipeline; why this model; what if this observation is removed?
- In tidyr and dplyr practice, keep predicting how many rows and columns the result should have before you run it.
See the AI Use Policy for the full rules.
