Interprets the results of a valid online controlled experiment, one whose harness, SRM, and telemetry have already been confirmed. Covers the distinction between practical and statistical significance, reading confidence intervals instead of binary p-values, novelty and primacy week-over-week decay that causes post-ship reversion, interaction effects from concurrent experiments, Simpson's paradox in segmented results, and the ordered guardrail-check sequence required before a ship decision. Use when a data scientist or PM is ready to draw conclusions from an experiment whose telemetry and randomisation have already passed the ab-test-validity-checklist. Distinct from ab-test-validity-checklist (harness setup and SRM detection) and from interaction-effect overlap auditing during experiment design.
