Power calculation for causal inference in social science: sample size and minimum detectable effect determination
3ie Working Paper 26, 2016
This manual, developed in-house by 3ie's Eric Djimeu and Deo-Gracias Houndolo, presents the basic statistical concepts used in power calculations for experimental design. The authors draw from real world examples to calculate statistical power for individual and cluster randomised controlled trials. The manual is accompanied by the Sample size and minimum detectable effect calculator©, a free online tool developed by the authors that allows users to work directly with each of the formulae presented in the manual.
