This is the only question I got stuck! My lecturer told me to go to G*power and produce (effect size)! We never went through it this way! It took me your video to get what I needed! Now I can either insert my own information here and work out effect study for my current research or use a previous data to determine my effect size :) so BIG THANK YOU from me :)

What could an interpretation be about the blue dotted distribution and the non-centrality parameter?

Thanks for sharing. I have a question. Do you know how can I use G*Power to calculate my sample size in a design with three groups (two experimental and one control) with a moderator and a mediator where both are continuous?

This is really great, thank you! Any suggested tutorials for how to do a post-hoc power analysis for repeated measures ANOVA?
