🧪 Visualizer Gallery
Every SIGMA chapter ships a hands-on Visualizer — a domain instrument in the chapter's right-hand panel. This page gathers all – instruments in one place so you can open each live, and leave structured feedback that agents can act on.
Each card lists the module's chapters (R/Py badges → live pages), its one-line design intent from the spec, and a ▶ open live expander that loads the real page in a frame. Jot a note + severity per instrument; your notes persist in this browser. When done, use the footer bar to download the JSON or copy a work order for Claude.
🧪 Live Labs
The weekly in-class instrument: a process that runs while you watch, which you detect, diagnose and treat in about thirty minutes. Each link below is that lab’s page. The labs themselves run on the course server and open with your Cornell login — if you are asked to sign in, that is expected.
- 🧪 FMEA Live Lab (sign-in)
A running operation re-judges occurrence and detection while severity holds, so criticality re-ranks under you. - 🧪 Descriptive Statistics Live Lab (sign-in)
A live stream whose centre and spread drift; read the summary statistics and say which one moved. - 🧪 Probability Live Lab (sign-in)
Watch the frequencies converge and put probability rules to work on a process that will not sit still. - 🧪 System Reliability Live Lab (sign-in)
Series and parallel blocks fail and get repaired live; find the block that actually sets system reliability. - 🧪 SPC Live Lab (sign-in)
The flagship lab — a streaming process you diagnose and treat on X̄ and S charts. - 🧪 Capability Live Lab (sign-in)
Specification limits meet a moving process; watch capability follow centring and spread. - 🧪 Useful Life Live Lab (sign-in)
Constant-hazard life data arriving in real time — estimate the rate and read what it predicts. - 🧪 Fault Tree Live Lab (sign-in)
Basic events flicker live; work the gates and find the cut set that carries the top event. - 🧪 Regression Live Lab (sign-in)
A relationship you fit while the data keeps coming, with a confounder that will happily fool you. - 🧪 Comparing Groups Live Lab (sign-in)
Two or more groups drift apart (or do not); decide whether the difference is real. - 🧪 Factorial Design & RSM Live Lab (sign-in)
Spend a fixed run budget on a factorial design and climb toward the summit by steepest ascent.
