![]() Clean up the tree in case you went too far in doing the splits. Stop it when you meet the stopping criteria.Again apply steps 1 and 2 to divide the data.The split test is any test that divides the data into two sets. Find a split that maximizes the separation of classes.Take the complete data set as the input.Elucidate the steps in making a Decision Tree.It is the interaction between the effects of input variable and output variable that differs among the levels of other factors. These are the Common Data Science Interview Questions that are asked to a fresher in an Interview. It is the method of approximating the value by extending the known set of facts or values.
