Hi Courtney, I recently shared your video with a statistics class that I'm currently taking because your explanation of the concepts is very good! However, I was told by my professor that in 6 minutes 13 seconds of the video the effect size of ANOVA use eta was indicated, but it should be eta squared. Again, your explanation of the concepts impacted my understanding to the degree that I shared the video with my class! Therefore, great job and thank you for the clarity of the concepts!!!

This is my new favourite video on youtube! I've bene struggling to get these concepts right for so long - you've put them in such a clear and logical way! Thank you so much!!

There might be a small mistake in one of the slides. At 6:00, first it's written as Cohen's "d" for small and then switches to (Pearson's ) "r" for medium and large.

Thank you! Have my "Like"

I've been doing Monte Carlo methods to estimate power of studies that are already published but did not report power. I don't see that as a waste of time because it helps me evaluate whether the study was likely to have missed an effect that other studies detected due to low power.

What if we don’t have the effect size (no previous studies available)?
