Question

Select all of the following statements that are true.

1. Correlation coefficients show the x and y intercepts of the best fit line.
2. Correlation coefficients show the relationship of the x and y values.
3. Correlation coefficients can be represented by the variable r.
4. Correlation coefficients are negative when the relationship is weak and positive when the relationship is strong.
5. Correlation coefficients can be any value less than 1 or greater than
-1.​

Answer 1

1. Correlation coefficients show the x and y intercepts of the best fit line.

3. Correlation coefficients can be represented by the variable r.

5. Correlation coefficients can be any value less than 1 or greater than -1.​

Answer 2

3. Correlation coefficients can be represented by the variable r

Explanation:

Correlation coefficients show if there is a strong or weak positive or negative relationship, or if there is no relationship between the variables.

Correlation coefficients are negative when the relationship is inversely proportional and positive when the relationship is proportional.

Correlation coefficients can be any value less than or equal to 1 or greater than or equal to -1.​
