    Thanks for the high quality video. Now that I am teaching online due to COVID-19, I sent this to my class to show how to set up a factorial RM ANOVA.
    One important correction:
    I'm not sure if this was just a mis-statement, but sphericity is not the equivalent of the normality assumption. Normality (of the residuals) is also an assumption of the RM ANOVA, but it is not related to sphericity. Sphericity is the RM equivalent of an equality of variances assumption.

      Eric, I'm glad that the videos are useful for you and your students. And you're absolutely right about my gaffe on sphericity! Thanks so much for pointing that out. I'll fix it in the future.

    Hi Bart, thanks for the explanations.
    I have one question tho: is there a way to display a size indicator (cohen's d) on the posthoc tests for a RM Anova?
    It seems that jamovi provides the option for Anova analyses, but I can't find a way to compute it for RM Anovas.
    Thanks!

    Hello, I have some statistical analysis I need to run and I believe I need to use Jamovi for it, but I don't know exactly what I am supposed to do or what I am doing wrong.
    I am analyzing data recorded by a group of subjects on two different days. The data is continuous. I used a paired t-test to test if there was statistical significance in the difference between the values from one day to the other. Now, I want to split the subjects by gender and see if gender plays a role in whether or not the difference in data from one day to the next is statistically significant. I believe this means I should be using a repeated measures ANOVA, but I can't seem to get how to use it. In this example you used two different nominal groups to split the data, but in my assessment I need to have the data from two different days split into gender respectively. How can I do that?

      There is a jamovi module that wasn't available at the time of this tutorial release date that may be of help to you. It is available after updating to the latest version of jamovi. You can update to the latest jamovi version here: www.jamovi.org/download.html
      The module is called "GAMLj - General Analyses for Linear Models 1.0.4" and can be found via "Modules" which is located in the upper right-hand corner of jamovi. This is the blog post concerning the module: blog.jamovi.org/2018/11/13/introducing-gamlj.html

    Can someone help me understand why I have letters in my within-subjects effect table in the sum square and mean square column? Thank you.
