"G*Power for Independent Research"

4.5/5

What do you like best about G*Power?

G*Power was straight forward, easy to use, and user friendly for someone who is not a statistics expert. It allowed me to conduct an a priori power analysis to determine an appropriate sample size for my research study. I did not have the ability to hire a statistician to do this for me, so this resource was really helpful. The website also provides a ready-to-use citation. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. This allowed us to contribute quality research to our field. Review collected by and hosted on G2.com.

"The only tool for statistical power"

5/5

What do you like best about G*Power?

G*Power is free, simple to use, and incredibly user-friendly. I love that it is mac-friendly and can calculate power for different tests. There are very few tools that can help you calculate the power of an analysis, and help you determine the sample size that is required. Review collected by and hosted on G2.com.

What do you dislike about G*Power?

The interface is somewhat outdated and minimalistic. There are some things that can be hard to find because of that. Review collected by and hosted on G2.com.
