Lab 03: Palmer penguins

Lab 03 focuses on

  • using linear regression and statistical inference to draw conclusions about penguins living in Palmer Archipelago in Antarctica.

  • use the data to check conditions about the distribution of the model residuals.

Use this week to get started on the lab. We will continue discussing statistical inference in this week’s lectures, so this lab will be due on Thursday, October 3, 2024.

Final Team Project

Goal: Use the methods from STA 221 to analyze data and answer a research question developed by your team

Primary deliverables:

  1. an in-person presentation about the exploratory data analysis and initial modeling
  2. a written, reproducible final report detailing your analysis
  3. a GitHub repository containing all work from the project

Submission: All work for the project will be submitted in your team’s GitHub repo. You will receive feedback via an Issue on GitHub to model a workflow often used in practice.

Final team project

Milestones: There are periodic project milestones throughout the semester to help you work towards the final deliverables:

  • Research questions (today’s lab)
  • Project proposal (next week’s lab)
  • Exploratory data analysis draft
  • Presentation + Presentation comments
  • Analysis draft + peer review
  • Round 1 submission (optional)
  • Written report
  • Reproducibility + organization

See the Final Project Instructions for a timeline and details for each milestone.

Today: Research questions

Goal: Develop three potential research questions your team may be interested in investigating.

You do not need to have a data set at this point

Reminder: Team workflow

  • Only one team member should type at a time. There are markers in today’s lab to help you determine whose turn it is to type.

    • Every team member should still be engaged in discussion for all questions, even if it’s not your turn type.

  • Don’t forget to pull to get your teammates’ updates before making changes to the .qmd file.

    Important

    Only one submission per team on Gradescope. Read the submission instructions carefully!

Reminder: Tips for working on a team

  • Do not pressure each other to finish early; use the time wisely to really learn the material and produce a quality report.

  • The labs are structured to help you learn the steps of a data analysis. Do not split up the lab among the team members; work on it together in its entirety.

  • Everyone has something to contribute! Use the lab groups as an opportunity to share ideas and learn from each other.
