When we create a Decision Tree, how is the best split determined at each node? Answer choices Select only one option We split the data using the first independent variable and so on. The first split is determined randomly and from then on we start choosing the best split. We make at most 5 splits on the data using only one independent variable and choose the split that gives the highest Gini gain. We make all possible splits on the data using the independent variables and choose the split that gives the highest Gini gain
