Block 4: Synthetic Validation & S3-S4 Lessons
Block 4: Synthetic Validation & S3-S4 Lessons
3 lessons from S3 (bias detection) and S4 (calendar optimization validation) implementation.
| # | Lesson | Core Teaching |
|---|---|---|
| 028 | Chi-Squared for Bias Detection | Distribution tests (chi-squared, binomial) detect planted biases at 100-voter scale without heavy machinery |
| 029 | Ground-Truth Recovery as Validation | Self-reported objective scores are circular; measure recovery of known-good items for external validation |
| 030 | Reliability Delta as Noise Measurement | Alpha(all) vs Alpha(clean) isolates noise from genuine preference diversity |
