In simple linear regression:
| a. |
The size of the coefficient for each IV gives you the size of the effect that variable has on the DV. |
|
| b. |
The sign of the coefficient gives you the direction of the effect. |
|
| c. |
With a single IV, the coefficient tells you how much the DV is expected to increase or decrease when the IV increased by one unit. |
|
| d. |
All of the above |
Homework Answers
a. The size of the coefficient for each IV gives you the size of the effect that variable has on the DV---This is a correct statement.
b. The sign of the coefficient gives you the direction of the effect----This is again correct statement.
c. With a single IV, the coefficient tells you how much the DV is expected to increase or decrease when the IV increased by one unit---This is also correct statement.
Hence correct option is (d) All of the above.

Answer both questions please true or false 16. The slope of the simple linear regression equation represents the average change in the value of the dependent variable per unit change in the independent variable (X). True/False 19. When using simple regression analysis, if there is a strong correlation between the independent and dependent variable, then we can conclude that an increase in the value of the independent variable causes an increase in the value of the dependent variable.
