Schedule (topic flow)
A 15-week pacing plan — Blackboard is authoritative for dates and deadlines
This is a pacing plan, not a calendar. It shows the order in which design topics unfold and roughly when, so you can read ahead and see where you are headed. It is not the authoritative calendar: exact dates, deadlines, and any mid-term adjustments live in Blackboard (the LMS), which is authoritative. A few fixed semester dates are noted for orientation only — confirm everything against Blackboard.
The course runs fifteen weeks in four parts. Each part below lists its weeks, the theme for each week, and the throughline — the design question that carries the week. The theme links to that week’s note.
Part I — Questions, measurement & validity (Weeks 1–4)
We set up the frame: what a statistical question is, how we measure, the signature distinction between sampling and assignment, and the threats a claim must survive.
| Week | Theme | The throughline |
|---|---|---|
| 1 | Statistical questions & units of analysis | What is the question, what is the unit, and what claim is being made? |
| 2 | Measurement & operational definitions | How do we turn an idea into observable data without pretending measurement is automatic? |
| 3 | Random sampling vs random assignment | Which mechanism is present, and does it earn a population claim or a causal one? |
| 4 | Bias, confounding & validity | What threatens a claim — and is the design internally or externally valid? |
Note: Labor Day (Mon, Sep 7) falls in Week 3 — no class that Monday, so the week runs Wednesday and Friday.
Part II — Designed experiments (Weeks 5–8)
We build the experimental machinery: randomized comparisons, then the refinements that sharpen and structure them.
| Week | Theme | The throughline |
|---|---|---|
| 5 | Completely randomized experiments | Why does random assignment license a causal claim, and how do we read the comparison? |
| 6 | Blocking & paired designs | How do we sharpen the same effect by removing nuisance variation? |
| 7 | Factorial experiments (midterm) | How do two factors at once give us main effects efficiently? |
| 8 | Interactions in designed studies | When does the effect of one factor depend on another? |
Note: the midterm is Friday, Oct 9 (in class), during Week 7. It covers statistical questions through factorial designs. No graded content appears on this public site — see Blackboard.
Part III — Observational & causal evidence (Weeks 9–10)
We move to studies without random assignment, where confounding lurks and causal diagrams keep the reasoning honest.
| Week | Theme | The throughline |
|---|---|---|
| 9 | Observational studies | When there’s no assignment, when can adjustment turn association toward causation? |
| 10 | Causal diagrams & backdoor reasoning | What should we adjust for — and what is a “bad control”? |
Part IV — Surveys, sampling & synthesis (Weeks 11–15)
We add survey sampling and missing data, then critique and synthesize the whole arc.
| Week | Theme | The throughline |
|---|---|---|
| 11 | Surveys & sampling frames | What does the sampling frame, coverage, and nonresponse let a survey claim? |
| 12 | Stratified & cluster sampling | How do sampling designs change the precision of a population estimate? |
| 13 | Missing data & nonresponse | How sensitive is a conclusion to who is missing, and why? |
| 14 | Study critique & design-memo workshop | How do you critique a claim and write a memo bounded by what the design supports? |
| 15 | Final design memo & review | How do experiments, observational studies, and surveys fit as one practice of evidence? |
Note: fall break is Nov 22–28 (no classes), between Weeks 13 and 14. The last class is Mon, Dec 7, the consultation day is Dec 8, and the final-exam window is Dec 9–15 (exact block via Blackboard).
Again: this page is a pacing plan to help you read ahead. For the real calendar — every date, every deadline, and any adjustment during the term — Blackboard (the LMS) is authoritative.
