A) A Pearson's product moment correlation of +1.00
B) A Pearson's product moment correlation between zero and +1.00
C) A Pearson's product moment correlation of zero
D) A Pearson's product moment correlation between zero and -1.00
E) A Pearson's product moment correlation of -1.00

A Pearson's product moment correlation of +1.00 indicates a perfect positive linear relationship between two variables. If every Y-score is exactly one-half its paired X-score, it means that as X increases, Y increases in a perfectly predictable manner (though at a different scale), which is a perfect positive linear relationship.

If Every Y-Score Is Exactly One-Half Its Paired X-Score, We
