There are 16
decision tree algorithms like ID3, J48, ADT etc. implemented
in WEKA. The algorithm used for classification is ID3, C4.5
and CART. Under the "Test options", the 10-fold crossvalidation
is selected as our evaluation approach. Since there
is no separate evaluation data set, this is necessary to get a
reasonable idea of accuracy of the generated model. The
model is generated in the form of decision tree. These
predictive models provide ways to predict whether a new
student will perform or not
