Thanks Chris for the great work you're doing. Could you please share the reference you're using to work with Dixon's test??? I couldn't find the paper giving the critical Q for sample size 100.

Thank you for your video, I have a question, I am not clear if I can apply the Grubbs test in spite of my dataset are not normally? it supposed that Grubb test is just for normal population dataset. Could you please clarify to me? Thank you
