Classification predicts categorical variables

WebRegression trees are used when the dependent variable is continuous while classification trees are used when the dependent variable is categorical. In continuous, a value obtained is a mean response of observation. In classification, a value obtained by a terminal node is a mode of observations. There is one similarity in both cases.
