Hello Mark,
thanks for your quick reply.
On Friday I figured out an even better solution for my problem: I found the mistake we did in the measurement.. now the outlier is gone.
But for the sake of this topic:
No, I tried all three commands Hide and Exclude, Exclude and Hide. For the box plot Hide and Exclude and Exclude gave the same result. Both times the outlier was not included in the calculation but also not visible. When I switched to points plot however it worked as I expected it.
When I tried Hide instead, the whole box plot disappeared..
I recreated the scenario and attached some screenshots. The abbreviations are clear I hope.
