You are building a classification tree for a binary outcome (Class A and Class B). A node currently contains 10 observations: 8 from Class A and 2 from Class B. Calculate the Gini Impurity of this node.(Hint: G i n i = 1 − ∑ k = 1 K p k 2 {“version”:”1.1″,”math”:”Gini = 1 – \sum_{k=1}^{K} p_k^2″} , where pk is the proportion of class k. Please provide all your answer as a two-digit decimal (e.g., 0.73.).
