Question

question 32
which of the following represents a strong negative correlation?
-0.2
+0.2
-0.9
+0.9

Explanation:

To determine a strong negative correlation, we use the correlation coefficient \( r \). A negative sign indicates a negative correlation, and the magnitude (absolute value) indicates strength. Values closer to -1 (or 1 for positive) are stronger. Among the options: -0.2 is weak negative, +0.2 is weak positive, +0.9 is strong positive, and -0.9 is strong negative (since it has a negative sign and a large magnitude close to -1).

Answer:

-0.9 (the option with -0.9, e.g., if the options are labeled as: C. -0.9, then the answer is C. -0.9)
