Question

which value of r represents data with a strong negative correlation between two data sets? -0.14 0.92 -1.07 -0.89

Explanation:

1. The correlation coefficient $r$ must be between $-1$ and $1$, so $-1.07$ is invalid.
2. A negative $r$ indicates negative correlation, eliminating $0.92$.
3. Values of $r$ closer to $-1$ mean a stronger negative correlation. $-0.89$ is much closer to $-1$ than $-0.14$.

Answer:

-0.89
