FAQ: How do you run a Monte Carlo power analysis for simple, serial and parallel mediation models?

Schoemann et al. created an easy to use web app that allows you to use Monte Carlo simulation to calculate sample size based on target power for the following models:

1. simple mediation
2. two parallel mediators
3. two serial mediators
