Group Activity: Explain It! Factorial Experiments

An in-class activity from the course slides — reproduced here so you can find it again after class.

📋 What to do

  1. Your group picks one of the five factorial design datasets used in code/13_examples.R: Plant Growth (2×2), Battery Life (2³), Website Purchases (2³), Bikeshare Usage (fractional 2^(3−1)), or Drone Flight Time (3×3).
  2. Using functions/functions_factorial.R (or the .py equivalent), compute the factorial effects, calculate standard errors, test significance, and interpret your results.
  3. Open your dataset in Team Boards and build your group's slide there.
  4. Fill it in with your group's answers about the factorial experiment.

📮 Submit

Please be sure to submit your group's response on CANVAS (1 pt) — graded on completion.

Note: these instructions are the current version — the activity is written and kept up to date on this page, links to slide decks and helper materials included. Submit on Canvas; the due date and your grade live there.
