Hello everyone!
So I'm trying to help my friend with power analysis, but because I don't really have the time to go through all my old books, I was just wondering if anyone could help me out with this.
I have data from 6 previous studies and I need to use them in order to calculate my effect size for a new study. How can I combine all my previous data in one effect size?
Thank you in advance
