Question 10

+1 markOne correct option

Say you build a multiple regression model using 6 independent variables and 20 data points. This is called Model-1. The R-Square for Model-1 is 94%. You then decide to add four more variables (such that the sample size is still 20) to the model and develop a new model called Model-2. The R- Squared for Model-2 is 95%. Then which of the following statements is/are TRUE?

  1. A

    Model-1 is better as it has lower R-Squared

  2. B

    Model-1 is better as it has lower Adjusted R-Square

  3. C

    Model-1 is better as it has higher Adjusted R-Square

  4. D

    Model-2 is better as it has higher R-Square

  5. E

    Model-2 is better as it has lower Adjusted R-Square

  6. F

    Model-2 is better as it has higher Adjusted R-Square

  7. G

    None of these
