The ______ measures the random variation,which is the variation of the actual (observed)y values from the predicted y values (ŷᵢ).
A)correlation coefficient
B)error sum of squares (SSE)
C)coefficient of determination
D)standard error of the estimate

Question

Quizplus · Accepted Answer

The standard error of the estimate measures the random variation or the scatter of the actual y values around the predicted y values. The error sum of squares (SSE) measures the total variation, not just the random variation. The correlation coefficient and coefficient of determination measure the strength and direction of the linear relationship between two variables.
