If all the points of a scatter diagram lie on the least squares regression line, then the coefficient of determination for these variables based on these data

A) is 0.
B) is 1.
C) is either 1 or -1, depending upon whether the relationship is positive or negative.
D) could be any value between -1 and 1.

Coefficient Of Determination

A statistical measure represented as R², which indicates the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

Least Squares Regression Line

The least squares regression line is a straight line that minimizes the sum of the squared differences between the observed values and the values predicted by the line.
