Question
Which of the following statements are not true about the sample correlation coefficient r?
The value of r depends on which of the two variables under study is labeled x and which is labeled y.
The value of r is independent of the units in which x and y are measure.
The value of r is always between -1 and +1, inclusive.
The value of r = 1 if all (Xi,Yi) pairs lie on a straight line with positive slope.
The value of r = -1 if all (Xi, Yi) pairs lie on a straight line with negative slope.
