Hi, I'm looking for help on an error that occurs when running a t-test. error capture [here] (https://www.dropbox.com/s/l0tp0kngnjr0p4i/Capture%20d’écran%202020-06-30%20à%2017.45.42.png?dl=0).
This error only occurs when we include a specific subject in the t-test, and I don't understand where this error can come from. Do you have any idea?
Thank you for your help,
Sophie
