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

📋 What to do

  1. Your group has been assigned 1 of the 11 Statistical Process Control questions below.
  2. 0.1 Open the Team Boards and choose the topic “Statistical Process Control”.
  3. 0.2 Pick the problem for your team's question. (Forgot your team number? Check at Canvas >> People >> Finalized Groups.)
  4. 0.3 Put your team name and your members in the header first, before you write anything else — that is what makes the board yours and what we present from.
  5. 1. Answer your question in the Notes pane; put any code in the Code pane. The questions:
    • Q1. What's the difference between x, x̄, x̿? How do you calculate them?
    • Q2. How do you make a process overview chart? (Exclude histogram)
    • Q3. How do we use ggarrange() and its arguments?
    • Q4. What is σshort? How do we calculate it for x̿?
    • Q5. What is σtotal? How do we calculate it for x̿?
    • Q6. How do we draw an average chart?
    • Q7. What are mR & mR̄? How does diff() help you find them?
    • Q8. What are d2 & d3? How do find them when n >= 2?
    • Q9. What does the dn function do? Walk me through each line.
    • Q10. How do we find d2 and d3 when subgroup size n = 1?
    • Q11. How do we draw a moving range chart?
  6. 2. Press Save, then Copy for Canvas, and paste it into the Canvas card.
  7. We present straight from the boards in the presenter view — about 2 minutes per team.
