D)either +1.00 or -1.00

Question

Quizplus · Accepted Answer

A perfect linear relationship between two variables X and Y would result in a correlation coefficient (robs) of either +1.00 or -1.00. This means that a change in one variable (X) will result in a perfectly predictable change in the other variable (Y), either in the same or opposite direction. A value of 0 indicates no linear relationship between the two variables, while values between 0 and +1.00 or 0 and -1.00 indicate weaker or partial linear relationships.
