Answer:

3. Correlation coefficients can be represented by the variable r

Step-by-step 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.
