Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
We have a total of 140,234 individuals split across two treated groups and an untreated control group. With N = 46,745 per arm, we’re powered to distinguish a difference between arms of about 0.425 pp (sample sizes in this figure are per arm). For our Individual Experiment, we’re powered to distinguish a difference between the control and treatment groups of about 0.88 pp.
