In the equation for a regression line, the slope is the:
A) value for X when Y is equal to 0.
B) predicted value for Y when X is equal to 0.
C) amount that Y is predicted to increase for a one-unit increase in X.
D) z score of the amount that Y is predicted to increase as X increases.

Question

Quizplus · Accepted Answer

The slope in a regression equation represents the amount of change in the dependent variable (Y) that is predicted for a one-unit increase in the independent variable (X). Therefore, C is the correct choice. A and B are incorrect because they represent values at the intercept, not the slope. D is incorrect because it references z-scores, which are not used in regression equations.
