Answer:

The correlation coefficient "r" can range from -1 to 1, indicating the strength and direction of the association between two variables.

In this case, you have an "r" value of -0.23.

- An "r" value closer to 1 indicates a strong positive correlation, meaning that as one variable increases, the other tends to increase as well.

- An "r" value closer to -1 indicates a strong negative correlation, meaning that as one variable increases, the other tends to decrease.

- An "r" value close to 0 indicates a weak or no linear correlation between the variables.

In your case, -0.23 is closer to 0 than it is to -1 or 1, so it represents a weak negative correlation. Therefore, the correct description is:

3. weak negative
