Continuing with Statistical Power simulation in R

In the last blog post I created a simple simulation of statistical power (probability to identify effects when they are really there) calulation depending on the sample size and effect size (Cohen’s D using Will Hopkins effect levels).

Now I will continue with the simulations and create 10 ES (from 0xSD [Baseline group] to 1xSD) levels with sample sizes going from 5 to 100 in 5 increment. We are going to resample 2000x
