Hi, I hope someone can help me!
I'm doing a psychology experiment and due to the nature of the experiment it has been very hard to get many participants tested. I need to know if I've got enough to draw a solid conclusion from.
I have 4 participants doing 4 conditions, and there are 5 repetitions of each condition for each person. I need to find out if there is a significant difference between the averages of each condition. I'm using a within subjects ANOVA, and I guess I'll need to use t-tests to determine the differences between each individual condition?
Anyway, my main question is - will 4 participants be enough?
Thanks for your help!
