A glossary, a study-design reference, and a causal-diagram guide

These are the reference pages to keep open while you read the notes and work the labs — the design vocabulary, the families of study designs, and how to draw and read a causal diagram, all in one place.

• Design & causal-evidence glossary — the vocabulary used throughout the course, from the unit of analysis and the random-sampling-vs-random-assignment distinction to confounders, blocking, main effects and interactions, sampling frames, the design effect, and the MCAR/MAR/MNAR missing-data mechanisms, with a plain-language meaning for each.
• Study-design reference — a one-page summary that lays the design families (completely randomized, blocked, paired, factorial, observational, and survey sampling) side by side: what each controls, what claim it can support, and what threat it leaves open.
• Causal-diagram guide — how to draw and read a causal diagram: nodes and arrows, confounders, mediators, colliders, backdoor paths, adjustment sets, and bad controls.

These pages are orientation and study aids. For graded specifics — deadlines, submissions, and the operational details of the course — more lives in Blackboard (the LMS), which is authoritative.
