Title: Week 9 Overview — Start Here
Course: Introduction to Statistics (18-Week Generic Edition)

Welcome to Week 9: Midterm Week

This week looks different, on purpose. There's no new chapter, no quiz, no lab — instead, the first half of the course gets pulled into one story, rehearsed, and then checked with a 50-question midterm. Before the nerves start: the midterm is worth 5% of your grade. It's a checkpoint, not a verdict. Eight weeks of tutorials, labs, quizzes, discussions, and assignments — the actual grade engine — are already behind you. This week simply tells you (and your instructor) how well the first half consolidated, while there's plenty of term left to act on the answer.

The week's big question

"Can you walk up to any number in the wild — a rating, a rate, a bell curve — and run the right Weeks 1–8 move on it, start to finish?"

By the end of this week, you can…

- [ ] See the first half as one map — get data honestly (W1) → picture it (W2) → summarize it (W3) → relate it (W4) → weigh the chance (W5–6) → model it (W7–8).
- [ ] Run the classic moves cold: classify a variable, pick the honest summary, read a two-way table with the right denominator, price an event with the four probability word-cues, compute E(X), np, √(np(1−p)), and take a normal model in both directions.
- [ ] Name the eight classic traps (the exam's distractors are built from them) — and dodge each one.
- [ ] Sit a cumulative exam with a plan — and walk out with information instead of just relief.

What to do this week, in order

The table below lists the week's items in working order — the order matters this week more than any other.

# | Do this | Type | Due
1 | Read the Study Guide — diagnose first: work its "Can you…?" checklists and mark your weak spots | Page (ungraded prep) | Start of the week
2 | Attend the review session (Session 1) — the map, rapid-fire drills, two integration examples, the misconception clinic, and exam logistics; the review deck mirrors it | Prep (ungraded) | Session 1
3 | Take the Practice Exam — 25 fresh items, unlimited attempts, feedback after each try; it shares zero items with the real exam | Practice · ungraded (Practice exercises, 0%) | At least one closed-book attempt before the exam
4 | Exam-Prep Tutorial 9 — your chatbot diagnoses all eight weeks, drills your weak spots, and ends with a 10-question mock round; submit the share link + Completion Summary | Tutorial · graded (Lecture tutorials, 20% group) · 10 pts | On or before exam day (mid-week)
5 | Take the Midterm — 50 questions × 2 points, Weeks 1–8, one attempt, closed to AI | Exam · graded (Midterm group, 5%) · 100 pts | Mid-week (day 4), per your instructor's window
6 | Discussion 9 — "The Midterm Mirror" — debrief the exam with your chatbot: what held, what wobbled, what changes; post the AI summary + chat link, then reply to two classmates | Discussion · graded (Discussions, 15% group) · 10 pts | Initial post two days before week's end; replies by end of Week 9
7 | Optional targeted repair — for anything that wobbled, revisit that week's chapter section and its tutorial drills | Prep (ungraded) | Rolling

The AI heads-up for exam week: the practice exam, the exam-prep tutorial, and the debrief discussion are AI-open — that's where the learning and the reflection happen. The midterm itself is closed to AI, exactly like the weekly quizzes. Calculator fine; one page of notes if your instructor permits it; any z-table values an item needs are printed inside that item. The only numbers worth memorizing: 68 – 95 – 99.7.

Late-policy reminder: 10% off per day for late submissions — and the midterm itself is time-bound, with make-ups only for documented emergencies. If life happens this week, contact your instructor before the exam window, not after.

How to succeed this week

- Diagnose, don't reread. The study guide's checklists find your actual weak spots in 45 minutes; rereading all eight chapters finds nothing and takes all week.
- Rehearse under exam conditions once. One closed-book, no-AI practice-exam attempt tells you more than three open-book ones. Unlimited retakes mean the first one is free.
- Let the tutorial do the drilling. It re-teaches what the practice exam catches — that division of labor (practice finds, tutorial fixes) is the whole design.
- Study the traps, not just the topics. Every distractor on the midterm is a named misconception from Weeks 1–8. Knowing the eight traps is legitimate exam strategy.
- Keep the stakes in view. 5%. Steady weekly work has carried you here and keeps carrying you. Walk in curious about what held.

After the exam: post your debrief while the experience is fresh. Week 10 opens the second half — what can a sample really tell us about the world it came from? — and it builds directly on the normal model you just mastered.
