Review on G*Power by Seth Gomez

I like that it takes out all of the math work it would take me hours (if not days) to calculate this stuff. It's easy enought you don't have to learn anything but basic addition/subtraction skills like multiplication/division and powers with numbers over 5 or so in order get any use from them. Nothing really! This software works great if your looking at small sample size studies without much variance amongst subject matter as well as medium to large sized studies. If there are variables such as repeated measures where each participant does one test then it gets very time consuming trying to figure up how big my n needs to become before i'm satisfied with statistical significance - which most people I know hate doing anyway. I like the way it is designed and how easy to use it is. It is very good for the statistical analysis of the data. I have not found any problem or dislike. It is very good and I recommend it to anyone who needs to use statistics. I am using it in my master thesis and it is very useful. I have used it to analyze the data of the experiments that I have done in the lab. It is very useful to me because of its simplicity.
