How to run ANOVA in this case with repeated measures?
I am looking for help how to set up JASP in the following case:
a cress test has been run with 4 different substrates and 4 different levels of a material called FerroSorp. In every Petri dish 10 seeds where placed. After the experiment the root length of each seed in all the different variants was measured. Every variant has three reps (=Petri dishes). Now I would like to run an ANOVA that compares the data without starting with the average of each Petri dish but instead using the information of all the 10 seeds in each dish. How do I have to set up this? Please find the csv data attached. I guess it's a repeated measure ANOVA but am not sure how to set the inputs right :/ Many thanks for Your help.
