🔧 Week 14 is in preparation. What follows is the plan for the 3-hour session — objectives, the Part 1 sections, the Part 2 exercise outline and the slide outline. Nothing here is counted yet.
Week 14 · Applied Statistics · HEG Genève

Weeks 7–12, by hand

The second drill week: hypothesis tests, two-sample problems, regression, chi-square and ANOVA — the exam's last three exercises. The hardest skill is not any single computation; it is choosing the procedure from the wording. That decision tree is the week.

🏫 In class: 3 h · lesson ~1 h, then exercises ~2 h 📖 Weeks 7–12 ▶ The Lecture button shows the slide outline

By the end of Week 14 you will be able to

  • Choose the test from the wording: one mean or two, paired or independent, proportion or mean, categories or numbers.
  • Run any test of the course with a rejection region and with a p-value.
  • Fit and interpret a regression line, and test its slope.
  • Read a contingency table and an ANOVA table.

Section 14.1 · The plan

What this week is for

Planned · Plan

A drill session on Weeks 7–12

  • Same format as Week 13: a timed set of three exam-style exercises, worked live; chosen from the dashboard's weakest questions.
Status → this section is an outline. When the week is written it becomes an interactive screen on the Week 1–2 pattern: an earned completion, a classify exercise or lab where one is listed, and its own share of the progress bar.
Section 14.2 · Which test?

The decision tree

Planned · Decide

Every procedure of the semester, on one page

  • Widget: a click-through tree — how many groups? numbers or categories? paired? — landing on the test and its exam card. Twelve pizzeria questions to route.
Status → this section is an outline. When the week is written it becomes an interactive screen on the Week 1–2 pattern: an earned completion, a classify exercise or lab where one is listed, and its own share of the progress bar.
Section 14.3 · Tests

Exam cards c13–c19

Planned · Drill

One-sample and two-sample tests

  • The trap list: tails, pooled vs unpooled, paired differences, "significant ≠ important".
Status → this section is an outline. When the week is written it becomes an interactive screen on the Week 1–2 pattern: an earned completion, a classify exercise or lab where one is listed, and its own share of the progress bar.
Section 14.4 · Regression and chi-square

Exam cards c20–c27

Planned · Drill

r, the line, the slope test, r², chi-square, F, ANOVA

  • The interpretation drill: every number in an output, in one business sentence.
Status → this section is an outline. When the week is written it becomes an interactive screen on the Week 1–2 pattern: an earned completion, a classify exercise or lab where one is listed, and its own share of the progress bar.
Section 14.5 · Open questions

Bring what you could not do

Planned · Q&A

Q&A, worked live

  • A workbook field: the question type you still cannot do.
Status → this section is an outline. When the week is written it becomes an interactive screen on the Week 1–2 pattern: an earned completion, a classify exercise or lab where one is listed, and its own share of the progress bar.

Part 2 · Exercises

5 exercises, worked together

Planned · ~90 min

The second half of the session

When this week is written, each exercise below becomes a form on this page and a slide in the deck, generated from one array so the two can never disagree — and its solution opens when the instructor reveals it in class. Same engine as Weeks 1–2 (exercises.js).

  • Exercise 1 · Which test? — the tree  15 min
    twelve wordings routed to twelve procedures
  • Exercise 2 · Exercise 4 · a test  20 min
    one-sample, with a p-value and a conclusion sentence
  • Exercise 3 · Exercise 5 · two samples or regression  20 min
    paired vs independent, or a slope test
  • Exercise 4 · Exercise 6 · chi-square or ANOVA  20 min
    a contingency table or a four-group comparison
  • Exercise 5 · Interpretation drill  15 min
    every number in an output, in one business sentence
Status → outline only. Nothing here is interactive or counted yet.
