Excellent tutorial! Thank you very much. I had downloaded the Add in real statistics and it did not work properly for Games Howell. This work perfectly.
Thanks for the suggestion. Indeed the Real Statistics add in is very impressive and has a lot of nice built in functions that make life very easy. I'm still jealous on how he created the Studentized Range Distribution. However not everyone likes installing extra add-ins or cannot. Guess it depends on what you want. But perhaps good if I mention it in the description. The add in is free and available at www.real-statistics.com/.

Hello, I'm trying to find the test type/function to use for Games-Howell after installing Real Statistics.
I performed a Games-Howell post-hoc test with Excel and also with SPSS. But I don't know why the Standard Error aren't same......
hard to tell. If I copy my own example in SPSS I get the same std. error as the ones in the Excel (the ones in the right table, around 08:12).
