    Ingo, I saw your answer to this question, but I could not generalize it. In my case, I am using 10-fold cross-validation on batch and the performance metric I am using is Kappa. My models detect the presence or absence of a certain state from students. However, for a given state I have gotten kappa: 0.094 +/- 0.266 (micro average: 0.421). The difference is too big. Thus, I would like to know which one should I report 0.094 or 0.421?  Thank you for your help.

    Hi,
    The macro average.  The whole point about the 10-fold cross validation is to get to the macro average.  So if you report / compare performances created by cross validations, you should always use the macro average.
    Hope this helps,
    Ingo
