A)for a given set of X and Y scores there is more than one regression line when regressing Y onto X
B)a minimum of two data points must fall directly on the regression line
C)the equation for a regression line is defined by the slope and the intercept
D)a regression line has at least two intercepts

Quizplus · Accepted Answer

The equation for a regression line is defined by the slope (Beta) and the intercept (Alpha). Therefore, statement C is true. A regression line is a single line that best fits the data, so statement A is false. There is no requirement for a minimum of two data points to fall directly on the regression line, so statement B is false. Lastly, a regression line only has one intercept (the y-intercept), so statement D is false.
