    Good Morning Folks,
    I have to admit, the remarks made on many of these posts are always entertaining (the pancake bunny almost made me fall out of my chair laughing), and people who are new to SS should definitely do some of their own research before asking very vague questions, very simple methadology questions, or questions whose scope is larger than the Milky Way!  Then again, anyone with this approach to understanding SS will be defeated very quickly in a real environment, since SS deployment and projects are never “spoon-fed” in terms of driving quality and change.  Poor souls…SS is not a “plug and play” methadology.  Best wishes with a different career if you are not passionate and resourceful and show initiative.
    This post is certainly not meant to discourage people from asking questions that are specific and direct.  So, I think I have taken the time to research on my own, and still cannot find the answers to what I think is an appropriate and well-designed question for this discussion forum.
    Here’s my question:
    Can someone explain what the Z column in the output analysis for Attribute Gage R&R is (In Minitab 15, this is now Attribute Agreement Analysis), and how it should be used.  The Z column will be presented under the Fleiss’ Kappa Statistics report, and I generally focus on the Kappa value and p value, but how should I use the Z value?
    Thanks in advance, and I look forward to your response.  Whether you want to be polite about it or not ;>)

    There are not many references explaining what is being done there,
    but the null here is agreement is strictly by chance (Kappa is equal
    to 0)z is equal to Kappa-0 divided by SE Kappa Go run through an example and you’ll see it.

    If soneone doesn’t respond (sorry, I don’t know the answer), I have found that Minitab will answer your question directly and for free.  You just have to ask them.
    Good luck.
