I want to predict if the student will play cricket or not{Target Variable}.
Suppose I have 3 columns : Gender ,Class, Age.
We can see we have 2 categorical attributes and one continuous attribute. While deciding the split at root node I know that both categorical attributes can be compared traditionally using gini criterion. How should I split the continuous attribute and which criterion should I take into account for it to be considered as a competitor for being the root node against 2 categorical variables?
