The website also provides a ready-to-use citation. **What do you dislike about G*Power?** There was a lot to the website, and you have to know what tests you're looking to run in order for it to be helpful. If you're REALLY rusty on stats there's a little bit of a learning curve. **Recommendations to others considering G*Power:** You should have a basic understanding of statistics. If you do not, or if your stats knowledge is very rudimentary, you may want to consider finding a statistician as a resource to help you determine the best ways to use the program & ensure you're running tests appropriately. **What problems is G*Power solving and how is that benefiting you?** G*Power helped me to strengthen the design of my research power and ensure that we have enough subjects to allow for meaningful findings.
