# Summary on correctly classfied instances WEKA for a 10-fold cross-validation

I ran a 10-fold cross-validation BayesNet (but it could be any method in WEKA), and the output I got was (among other things):

My questions is related to the Correctly Classified Instances. In this case I got 142 out of 160, but on which run? To my knowledge, a 10-fold cross-validation runs several times. This statistic is for which run?

The best?

The last?

For all of them?

And if it was an average on all runs, don't you guys think that it's a little bit convenient that the number was a nice integer (I ran a lot of classifications and its always an integer).
