The correct answer is: Independent variables can be either categorical or continuous. Dependent variables must be continuous.In regression analysis, the independent variables can be either categorical or continuous, while the dependent variable must be continuous. The dependent variable is the outcome or the variable that we are trying to predict or explain, and it should be continuous in order to perform regression analysis. On the other hand, the independent variables are the variables that we use to predict or explain the dependent variable, and they can be either categorical or continuous.
