I’m glad you like the website!

]]>I just calculated your example in the second paragraph using G*Power (http://www.psycho.uni-duesseldorf.de/aap/projects/gpower/) and it tells me that the power of that particular test is 0.56. Im fairly certain I plugged in the correct numbers. So is G*Power wrong or are you?

By the way, this website is of tremendous help to me. I already ordered your book!

Kind regards,

Henk.
