A)the scores on X and Y are not related.

D)the differences between X and Y are statistically nonsignificant.

Question

A correlation of .80 indicates a strong positive relationship between two variables, meaning as scores on one variable increase, scores on the other variable tend to also increase in a linear fashion. The statement in choice B is a simplified way to describe this relationship, suggesting that there is a predictable change in Y for a given change in X, although it's not technically precise about how correlation coefficients work. Correlation does not imply the exact change in magnitude (like being 0.8 times) between X and Y, but it does indicate a strong linear relationship.
