Problem

What do you do if your experiment results are inconclusive in a data-driven project for Bunge Limited?

Explain how you would distinguish between no meaningful effect, insufficient power, poor instrumentation, and an invalid experiment. Address the primary metric, guardrails, MDE, sample-size assumptions, randomization unit, statistical analysis, and decision criteria. State how you would handle peeking, sample ratio mismatch, and inconclusive subgroup results. Use illustrative assumptions only where numerical calculations are required.

  1. Define the hypotheses and metrics.
  2. Show a power and sample-size calculation.
  3. Provide an analysis and diagnostic plan.
  4. Recommend a ship, iterate, or stop decision.
