Hi!
The values refer to the attribute that was selected for the split. In the first split, petal length, in the second one, petal width.
When a decision tree splits a numerical attribute, it searches for a value that cleanly separates a class from others. The values were automatically chosen.
In your case, you can read the tree like this:
If petal length is <= 1.9, then the class is Iris setosa.
If petal length is > 1.9 and petal width is <= 1.7, then the class is Iris versicolor in most of the cases.
Else it's Iris virginica.
Regards,
Balázs

Hi,
out of curiosity:
where does this image come from? This does not look like a RapidMiner screenshot?
Cheers,
