Power calculation: Minimum Detectable Effect Size for Main Outcomes
|
Before
Power calculations are calculated using data from previous experiments run on the platform. The main outcome of interests is the average donation across treatments. The standard deviation of the average donation in the sample was 15.5 euro. With 60.000 observations, the minimum detectable effect size is 0.0162 standard deviation for the average donation (alpha = 0. 5, power = 80%), which is about a 5.7% increase in the mean.
