Design and analysis of a shelf display test, drawn from working in a wholesale warehouse.
The problem

What I built
Sample size and statistical power calculated upfront, blocking by day of the week, and the correct unit of analysis to avoid pseudoreplication.
What changed
The significant result translates into projected incremental revenue, in pesos.
