Sample Size Calculation
For a two-sample proportions test:
n = 2 × (Z_α/2 + Z_β)² × p̄(1-p̄) / (δ)²Where:
- Z_α/2 = 1.96 for α=0.05 (two-tailed)
- Z_β = 0.84 for 80% power, 1.28 for 90% power
- p̄ = average of baseline and expected conversion rate
- δ = minimum detectable effect (MDE)
Always ask: What MDE is meaningful for the business?
