A decision tree is used to predict whether a student is likely to play football using the training data below. The algorithm uses the attribute selection method to identify the split that produces more sub-nodes that are homogeneous.

Calculate the Gini index and Information Gain for a split on Gender and a split of Class .Show all your steps.

Determine which split should be used on the decision tree (split for Gender or split for Class attribute) if you use:
