a linear regression equation of the form Y = a + bX,the slope parameter b shows
A)$\Delta$X / $\Delta$Y.
B)$\Delta$Y / $\Delta$X.
C)$\Delta$Y /$\Delta$b.
D)$\Delta$X / $\Delta$b.
E)none of the above

Question

Quizplus · Accepted Answer

The slope parameter b represents the amount of change in the dependent variable Y for a unit change in the independent variable X. So, b can be calculated as the ratio of the change in Y to the change in X. Therefore, b = (ΔY)/(ΔX). This implies that the correct option is B, as the slope parameter b can be calculated as the ratio of the change in Y to the change in X.
