A scatterplot has a correlation coefficient of r = -0.85. Which best describes the relationship?

The correlation coefficient has two parts. Its sign shows direction: negative means that as one variable increases, the other tends to decrease. Its size shows strength: values near $\pm1$ are strong and values near $0$ are weak. Here $r=-0.85$ is negative and close to $-1$, so it is a strong negative relationship, choice H. Choice F has the wrong direction. Choice G has the right direction but calls $0.85$ weak. Choice J (no relationship) would need $r$ near $0$. Note that correlation does not prove one variable causes the other.
