Question

Quizplus · Accepted Answer

The value b in the bivariate regression equation Y = a + bX is called the slope. It represents the change in Y for every one unit change in X, and is a measure of the strength and direction of the linear relationship between X and Y. The intercept (a) is the value of Y when X is equal to zero. The variance percentage and correlation coefficient are not directly related to the bivariate regression equation.
