I keep running the data through and it makes a binary decision, and only appears to use one attribute, which it doesn't specify. What am I missing in configuring the tree? Output is:
J48 pruned tree------------------: High (113.0/57.0)
Number of Leaves : 1
Size of the tree : 1
Time taken to build model: 0 seconds
