6, Using the CART algorithm to calculate the Gini Index of Diversity(a measure of impurity), the weighted average Gini Index of splitting(under specific attribute conditions), the reduction in impurity, and decide which attribute would be chosen for the splitting subset. Besides, compare the impurity reduction in the specific attribute calculation difference if using Frequency Table. Generate and draw a CART Decision Tree using the above information and the following dataset. Give used equations and computational processes
