Question

If there is a positive correlation between X and Y then in the regression equation,Y = bX + a,____. A)b > 0 B)b < 0 C)a > 0 D)a < 0

Quizplus · Accepted Answer

In a positive correlation, as X increases Y will also increase. In the regression equation Y = bX + a, the coefficient b represents the slope of the line and indicates the change in Y per unit increase in X. Since there is a positive correlation between X and Y, the slope of the line will also be positive, and therefore b > 0.
