Question

In a regression model, if every data point is exactly along the regression line, then
A. the coefficient of correlation would be 0
B. the coefficient of correlation would be -1 or 1
C. the coefficient of determination would be 0
D. the coefficient of determination would be -1

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
