The t-test in the multiple regression model:
(A) is used to test the presence of measurement errors in the data.
(B) is used to test for the presence of a non-linear relationship.
(C) is used to test the significance of all dependent variables.
(D) is used to test the significance of one dependent variable.
(E) none of the above is correct.
Homework Answers
Answer
The correct answer is (E) none of the above is correct.
The t test in the multiple regression model is used to check whether the independent variable has significant impact on the dependent variable. Thus t test in the multiple regression model is used to test the significance of an independent variable and not dependent variable.
Hence, the correct answer is (E) none of the above is correct.

Multiple regression procedures may be used when two or more interval-level measures serve as predictors of some normally distributed interval-level dependent variable. In this model, the regression coefficient for any independent or predictor variable (X1) represents the change in the dependent or outcome variable (Y) associated with one unit change in X1, while controlling for or maintaining other predictors (X2, X3, etc.) at constant. If you required to use this model in the analysis of the data of a research...

How does a bivariate regression model differ from a multiple regression model? Multiple Choice A bivariate regression has only one dependent and independent variable but a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has more than one dependent variable and only one independent variable where a multiple regression has one dependent variable and may have many independent variables. A bivariate regression has only one dependent and many independent variables but a multiple...
